-\section{Adding a station}
-\label{tutorial/adding_station:adding-a-station}\label{tutorial/adding_station::doc}
-You can change all your settings throught the \emph{admin section} of the website.
-To reach it, click on \textbf{Station admin} link at the main menu of the site.
-
-\begin{notice}{note}{Note:}
-You will need to have an account with admin access privilages to access this part of the site.
-See {\hyperref[user_management:user-management]{\emph{User management}}} for details.
-\end{notice}
-
-The first you have to do to start using the single calculus chain is to register your station.
-To do this, go the the admin section and click on the \textbf{HOI stations} in the \emph{System settings} panel.
-This will take you to a page with a list of all stations that you account has access to. This list should
-be empty if this is the first time you add a station.
-
-To add a new station to the database click on \textbf{Add HOI station} at the top right of the screen.
-This will take you to a new page were you can fill in the needed information. The fields in \textbf{bold}
-are mandatory and you will need to fill them before you can save you new station.
-
-For now you will need to fill in the following fields:
-\begin{description}
-\item[{Name}] \leavevmode
-The name of the station
-
-\item[{Id}] \leavevmode
-The earlinet call sign with exactly 2 characters.
-
-\item[{Institute name}] \leavevmode
-The name of the institute that own the system
-
-\item[{Latitude}] \leavevmode
-In degrees north is the latitude of the station.
-
-\item[{Longitude}] \leavevmode

-
-\item[{Height asl}] \leavevmode
-The altitude of the station in meters above sea level.
-
-\item[{PI}] \leavevmode
-The name of the Principal Investigator of the station.
-
-\end{description}
-
-You can leave all the other fields empty. When you are done, press the \textbf{save} button at the bottom right of the page.
-This will take you back to the list of your stations. If everything went OK your station you just added should appear
-in the list.
-
-We don't have to make any more changes in this part, so you can click on \textbf{Home}
-on the top left of the page to return to the starting page of the \emph{admin section}.
-
-
-\section{Adding a system}
-\label{tutorial/adding_system::doc}\label{tutorial/adding_system:adding-a-system}
-After adding a station to the database, we need to add a new system.
-To do this, click on the \textbf{HOI systems} in the \emph{System settings} panel.
-This will take you to a page with a list of all availabe systems that are connected with your stations. This list should
-be empty if this is the first time you add a system.
-
-\begin{notice}{note}{Note:}
-In the Single Calculus Chain, a \emph{HOI System} represents a specific configuration of a lidar system.
-For example, if you are operating a lidar system and you use different channels during daytime and nightime,
-you will need to register \emph{two different} systems in the database, one for each different configuration you use.
-\end{notice}
-
-To add a new system to the database click on \textbf{Add HOI system} at the top right of the screen.
-This will take you to a new page were you can fill in the needed information. As before, the fields in \textbf{bold}
-are mandatory and you will need to fill them before you can save you new system.
-
-\begin{notice}{note}{Note:}
-Not every field that is present in the database is used in the in the Single Calculs Chain.
-Many of them are part of the Handbook of Instruments.
-\end{notice}
-
-For now you will need to fill in the following fields:
-\begin{description}
-\item[{Name}] \leavevmode

-The Single Calculus Chain (SCC) is composed by two different modules:
-\begin{itemize}
-\item {}
-pre-processing module ( scc\_preprocessing)
-
-\item {}
-optical processing module ( ELDA)
-
-\end{itemize}
-
-To perfom aerosol optical retrievals the SCC needs not only the raw
-lidar data but also a certain number of parameters to use in both
-pre-processing and optical processing stages. The SCC gets these
-parameters looking at two different locations:
-\begin{itemize}
-\item {}
-Single Calculus Chain relational database (SCC\_DB)
-
-\item {}
-Input files
-
-\end{itemize}
-
-There are some paramenters that can be found only in the input files
-(those ones changing from measurement to measurement), others that can
-be found only in the SCC\_DB and other ones that can be found in both
-these locations. In the last case, if a particular parameter is needed,
-the SCC will search first in the input files and then in SCC\_DB. If the
-parameter is found in the input files the SCC will keep it without
-looking into SCC\_DB.
-
-The input files have to be submitted to the SCC in NetCDF format. At the
-present the SCC can handle four different types of input files:
-\begin{enumerate}
-\item {}
-Raw Lidar Data
-
-\item {}
-Sounding Data
-
-\item {}
-Overlap
-
-\item {}
-Lidar Ratio
-
-\end{enumerate}
-
-As already mentioned, the Raw Lidar Data file contains not only the
-raw lidar data but also other parameters to use to perform the
-pre-processing and optical processing. The Sounding Data file
-contains the data coming from a correlative radiosounding and it is used
-by the SCC for molecular density calculation. The Overlap file
-contains the measured overlap function. The Lidar Ratio file contains
-a lidar ratio profile to use in elastic backscatter retrievals. The
-Raw Lidar Data file is of course mandatory and the Sounding Data,
-Overlap and Lidar Ratio files are optional. If Sounding Data file
-is not submitted by the user, the molecular density will be calculated
-by the SCC using the “US Standard Atmosphere 1976”. If the Overlap
-file is not submitted by the user, the SCC will get the full overlap
-height from SCC\_DB and it will produce optical results starting from
-this height. If Lidar Ratio file is not submitted by the user, the
-SCC will consider a fixed value for lidar ratio got from SCC\_DB.
-
-The user can decide to submit all these files or any number of them (of
-course the file Raw Lidar Data is mandatory). For example the user
-can submit together with the Raw Lidar Data file only the Sounding
-Data file or only the Overlap file.
-
-This document provides a detailed explanation about the structure of the
-NetCDF input files to use for SCC data submission. All Earlinet groups
-should read it carefully because they have to produce such kind of input
-files if they want to use the SCC for their standard lidar retrievals.
-Every comments or suggestions regarding this document can be sent to
-Giuseppe D’Amico by e-mail at \code{damico@imaa.cnr.it}
-
-This document is available for downloading at \code{www.earlinetasos.org}
-
-In table tab:rawdata is reported a list of dimensions, variables and
-global attributes that can be used in the NetCDF Raw Lidar Data input
-file. For each of them it is indicated:
-\begin{itemize}
-\item {}
-The name. For the multidimensional variables also the corresponding
-dimensions are reported
-
-\item {}
-A description explaining the meaning
-
-\item {}
-The type
-
-\item {}
-If it is mandatory or optional
-
-\end{itemize}
-
-As already mentioned, the SCC can get some parameters looking first in
-the Raw Lidar Data input file and then into SCC\_DB. This means that
-to use the parameters stored in SCC\_DB the optional variables or
-optional global attributes must not appear within Raw Lidar Data
-file. This is the suggested and recommended way to use the SCC. Please
-include optional parameters in the Raw Lidar Data only as an
-exception.
-
-In table tab:sounding, tab:overlap and tab:lr are reported all the
-information about the structure of Sounding Data, Overlap and
-Lidar Ratio input files respectively.

-\section{Example}
-\label{netcdf_file:example}
-Let’s now consider an example of Raw Lidar Data input file. Suppose
-we want to generate NetCDF input file corresponding to a measurement
-with the following properties:
-
-\begin{tabulary}{\linewidth}{|L|L|}
-\hline

-Moreover suppose that this measurement is composed by the following

-\begin{enumerate}
-\item {}

-\\\hline
- \multicolumn{2}{|l|}{
-Range resolution=15m

-\end{tabulary}
-
-
-\end{enumerate}
-
-Finally let’s assume we have also performed dark measurements before the
-lidar measurements from the 23:50:01 UT up to 23:53:01 UT of
-29:math:\emph{\textasciicircum{}mathrmth} January 2009.
-
-
-\subsection{Dimensions}
-\label{netcdf_file:dimensions}
-Looking at table tab:rawdata we have to fix the following dimensions:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{points}
-\PYG{n}{channels}
-\PYG{n}{time}
-\PYG{n}{nb\PYGZus{}of\PYGZus{}time\PYGZus{}scales}
-\PYG{n}{scan\PYGZus{}angles}
-\PYG{n}{time\PYGZus{}bck}
-\end{Verbatim}
-
-The dimension \code{time} is unlimited so we don’t have to fix it.
-
-We have 4 lidar channels so:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{channels}\PYG{o}{=}\PYG{l+m+mi}{4}
-\end{Verbatim}
-
-Regarding the dimension \code{points} we have only one channel with a
-number of vertical bins equal to 3000 (the 1064nm) and all other
-channels with 5000 vertical bins. In cases like this the dimension
-\code{points} has to be fixed to the maximum number of vertical bins so:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{points}\PYG{o}{=}\PYG{l+m+mi}{5000}
-\end{Verbatim}
-
-Moreover only one channel (1064nm) is acquired with a time resolution of
-30 seconds, all the other channels have a time resolution of 60 seconds.
-This means that we have to define two different time scales. We have to
-set:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{nb\PYGZus{}of\PYGZus{}time\PYGZus{}scales}\PYG{o}{=}\PYG{l+m+mi}{2}
-\end{Verbatim}
-
-The measurement is performed only at one scan angle (5 degrees with
-respect to the zenith) so:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{scan\PYGZus{}angles}\PYG{o}{=}\PYG{l+m+mi}{1}
-\end{Verbatim}
-
-We have 3 minutes of dark measurements and two different time scales one
-with 60 seconds time resolution and the other one with 30 seconds time
-resolution. So we will have 3 different dark profiles for the channels
-acquired with the first time scale and 6 for the lidar channels acquired
-with the second time scale. We have to fix the dimension \code{time\_bck} as
-the maximum between these values:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{time\PYGZus{}bck}\PYG{o}{=}\PYG{l+m+mi}{6}
-\end{Verbatim}
-
-
-\subsection{Variables}
-\label{netcdf_file:variables}
-In this section it will be explained how to fill all the possible
-variables either mandatory or optional of Raw Lidar Data input file.
-\begin{description}
-\item[{Raw\_Data\_Start\_Time(time, nb\_of\_time\_scales)}] \leavevmode
-This 2 dimensional mandatory array has to contain the acquisition
-start time (in seconds from the time given by the global attribute
-\code{RawData\_Start\_Time\_UT}) of each lidar profile. In this example we
-have two different time scales: one is characterized by steps of 30
-seconds (the 1064nm is acquired with this time scale) the other by
-steps of 60 seconds (532cross, 532parallel and 607nm). Moreover the
-measurement start time is 00:00:01 UT and the measurement stop time
-is 00:05:01 UT. In this case we have to define:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-Raw\_Data\_Start\_Time =
- 0, 0,
- 60, 30,
- 120, 60,
- 180, 90,
- 240, 120,
- \_, 150,
- \_, 180,
- \_, 210,
- \_, 240,
- \_, 270 ;
-\end{Verbatim}
-
-The order used to fill this array defines the correspondence between
-the different time scales and the time scale index. In this example
-we have a time scale index of 0 for the time scale with steps of 60
-seconds and a time scale index of 1 for the other one.
-
-\item[{Raw\_Data\_Stop\_Time(time, nb\_of\_time\_scales)}] \leavevmode
-The same as previous item but for the data acquisition stop time.
-Following a similar procedure we have to define:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-Raw\_Data\_Stop\_Time =
- 60, 30,
- 120, 60,
- 180, 90,
- 240, 120,
- 300, 150,
- \_, 180,
- \_, 210,
- \_, 240,
- \_, 270,
- \_, 300 ;
-\end{Verbatim}
-
-\item[{Raw\_Lidar\_Data(time, channels, points)}] \leavevmode
-This 3 dimensional mandatory array has to be filled with the
-time-series of raw lidar data. The photoncounting profiles have to
-submitted in counts (so as integers) while the analog ones in mV. The
-order the user chooses to fill this array defines the correspondence
-between channel index and lidar data.
-
-For example if we fill this array in such way that:
-
-\begin{tabulary}{\linewidth}{|L|L|}
-\hline
-
-Raw\_Lidar\_Data(time,0,points
- &
-$\rightarrow$ is the time-series of 1064 nm
-\\\hline
-
-Raw\_Lidar\_Data(time,1,points
- &
-$\rightarrow$ is the time-series of 532 cross
-\\\hline
-
-Raw\_Lidar\_Data(time,2,points
- &
-$\rightarrow$ is the time-series of 532 parallel
-\\\hline
-
-Raw\_Lidar\_Data(time,3,points
- &
-$\rightarrow$ is the time-series of 607 nm
-\\\hline
-\end{tabulary}
-
-
-from now on the channel index 0 is associated to the 1064 channel,
-1 to the 532 cross, 2 to the 532 parallel and 3 to the 607nm.
-
-\item[{Raw\_Bck\_Start\_Time(time\_bck, nb\_of\_time\_scales)}] \leavevmode
-This 2 dimensional optional array has to contain the acquisition
-start time (in seconds from the time given by the global attribute
-\code{RawBck\_Start\_Time\_UT}) of each dark measurements profile.
-Following the same procedure used for the variable
-\code{Raw\_Data\_Start\_Time} we have to define:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-Raw\_Bck\_Start\_Time =
- 0, 0,
- 60, 30,
- 120, 60,
- \_, 90,
- \_, 120,
- \_, 150;
-\end{Verbatim}
-
-\item[{Raw\_Bck\_Stop\_Time(time\_bck, nb\_of\_time\_scales)}] \leavevmode
-The same as previous item but for the dark acquisition stop time.
-Following a similar procedure we have to define:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-Raw\_Bck\_Stop\_Time =
- 60, 30,
- 120, 60,
- 180, 90,
- \_, 120,
- \_, 150,
- \_, 180 ;
-\end{Verbatim}
-
-\item[{Background\_Profile(time\_bck, channels, points)}] \leavevmode
-This 3 dimensional optional array has to be filled with the
-time-series of the dark measurements data. The photoncounting
-profiles have to submitted in counts (so as integers) while the
-analog ones in mV. The user has to fill this array following the same
-order used in filling the array \code{Raw\_Lidar\_Data}:
-
-\begin{tabulary}{\linewidth}{|L|L|}
-\hline
-
-Background\_Profile(time\_bck,0,points
- &
-$\rightarrow$ dark time-series at 1064 nm
-\\\hline
-
-Background\_Profile(time\_bck,1,points
- &
-$\rightarrow$ dark time-series at 532 cross
-\\\hline
-
-Background\_Profile(time\_bck,2,points
- &
-$\rightarrow$ dark time-series at 532 parallel
-\\\hline
-
-Background\_Profile(time\_bck,3,points
- &
-$\rightarrow$ dark time-series at 607 nm
-\\\hline
-\end{tabulary}
-
-
-\item[{channel\_ID(channels)}] \leavevmode
-This mandatory array provides the link between the channel index
-within the Raw Lidar Data input file and the channel ID in
-SCC\_DB. To fill this variable the user has to know which channel IDs
-in SCC\_DB correspond to his lidar channels. For this purpose the
-SCC, in its final version will provide to the user a special tool to
-get these channel IDs through a Web interface. At the moment this
-interface is not yet available and these channel IDs will be
-communicated directly to the user by the NA5 people.
-
-Anyway to continue the example let’s suppose that the four lidar
-channels taken into account are mapped into SCC\_DB with the
-following channel IDs:
-
-\begin{tabulary}{\linewidth}{|L|L|}
-\hline
-
-1064 nm
- &
-$\rightarrow$ channel ID=7
-\\\hline
-
-532 cross
- &
-$\rightarrow$ channel ID=5
-\\\hline
-
-532 parallel
- &
-$\rightarrow$ channel ID=6
-\\\hline
-
-607 nm
- &
-$\rightarrow$ channel ID=8
-\\\hline
-\end{tabulary}
-
-\begin{quote}
-
-In this case we have to define:
-\end{quote}
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{channel\PYGZus{}ID} \PYG{o}{=} \PYG{l+m+mi}{7}\PYG{p}{,} \PYG{l+m+mi}{5}\PYG{p}{,} \PYG{l+m+mi}{6}\PYG{p}{,} \PYG{l+m+mi}{8} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{id\_timescale(channels)}] \leavevmode
-This mandatory array is introduced to determine which time scale is
-used for the acquisition of each lidar channel. In particular this
-array defines the link between the channel index and the time scale
-index. In our example we have two different time scales. Filling the
-arrays \code{Raw\_Data\_Start\_Time} and \code{Raw\_Data\_Stop\_Time} we have
-defined a time scale index of 0 for the time scale with steps of 60
-seconds and a time scale index of 1 for the other one with steps of
-30 seconds. In this way this array has to be set as:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{id\PYGZus{}timescale} \PYG{o}{=} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{0}\PYG{p}{,} \PYG{l+m+mi}{0}\PYG{p}{,} \PYG{l+m+mi}{0} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Laser\_Pointing\_Angle(scan\_angles}] \leavevmode
-This mandatory array contains all the scan angles used in the
-measurement. In our example we have only one scan angle of 5 degrees
-with respect to the zenith, so we have to define:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Laser\PYGZus{}Pointing\PYGZus{}Angle} \PYG{o}{=} \PYG{l+m+mi}{5} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Laser\_Pointing\_Angle\_of\_Profiles(time, nb\_of\_time\_scales)}] \leavevmode
-This mandatory array is introduced to determine which scan angle is
-used for the acquisition of each lidar profile. In particular this
-array defines the link between the time and time scales indexes and
-the scan angle index. In our example we have a single scan angle that
-has to correspond to the scan angle index 0. So this array has to be
-defined as:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-Laser\_Pointing\_Angle\_of\_Profiles =
- 0, 0,
- 0, 0,
- 0, 0,
- 0, 0,
- 0, 0,
- \_, 0,
- \_, 0,
- \_, 0,
- \_, 0,
- \_, 0 ;
-\end{Verbatim}
-
-\item[{Laser\_Shots(time, channels)}] \leavevmode
-This mandatory array stores the laser shots accumulated at each time
-for each channel. In our example the number of laser shots
-accumulated is 1500 for the 1064nm channels and 3000 for all the
-other channels. Moreover the laser shots do not change with the time.
-So we have to define this array as:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-Laser\_Shots =
- 1500, 3000, 3000, 3000,
- 1500, 3000, 3000, 3000,
- 1500, 3000, 3000, 3000,
- 1500, 3000, 3000, 3000,
- 1500, 3000, 3000, 3000,
- 1500, \_, \_, \_,
- 1500, \_, \_, \_,
- 1500, \_, \_, \_,
- 1500, \_, \_, \_,
- 1500, \_, \_, \_ ;
-\end{Verbatim}
-
-\item[{Emitted\_Wavelength(channels)}] \leavevmode
-This optional array defines the link between the channel index and
-the emission wavelength for each lidar channel. The wavelength has to
-be expressed in nm. This information can be also taken from SCC\_DB.
-In our example we have:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Emitted\PYGZus{}Wavelength} \PYG{o}{=} \PYG{l+m+mi}{1064}\PYG{p}{,} \PYG{l+m+mi}{532}\PYG{p}{,} \PYG{l+m+mi}{532}\PYG{p}{,} \PYG{l+m+mi}{532} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Detected\_Wavelength(channels)}] \leavevmode
-This optional array defines the link between the channel index and
-the detected wavelength for each lidar channel. Here detected
-wavelength means the value of center of interferential filter
-expressed in nm. This information can be also taken from SCC\_DB. In
-our example we have:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Detected\PYGZus{}Wavelength} \PYG{o}{=} \PYG{l+m+mi}{1064}\PYG{p}{,} \PYG{l+m+mi}{532}\PYG{p}{,} \PYG{l+m+mi}{532}\PYG{p}{,} \PYG{l+m+mi}{607} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Raw\_Data\_Range\_Resolution(channels)}] \leavevmode
-This optional array defines the link between the channel index and
-the raw range resolution for each channel. If the scan angle is
-different from zero this quantity is different from the vertical
-resolution. More precisely if $\alpha$ is the scan angle used
-and $\Delta z$ is the range resolution the vertical
-resolution is calculated as $\Delta
-z'=\Delta z \cos\alpha$. This array has to be filled with
-$\Delta z$ and not with $\Delta z'$. The unit is
-meters. This information can be also taken from SCC\_DB. In our
-example we have:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Raw\PYGZus{}Data\PYGZus{}Range\PYGZus{}Resolution} \PYG{o}{=} \PYG{l+m+mf}{7.5}\PYG{p}{,} \PYG{l+m+mf}{15.0}\PYG{p}{,} \PYG{l+m+mf}{15.0}\PYG{p}{,} \PYG{l+m+mf}{15.0} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{ID\_Range(channels)}] \leavevmode
-This optional array defines if a particular channel is configured as
-high, low or ultranear range channel. In particular a value 0
-indicates a low range channel, a value 1 a high range channel and a
-value of 2 an ultranear range channel. If for a particular channel
-you don’t separate between high and low range channel, please set the
-corresponding value to 1. This information can be also taken from
-SCC\_DB. In our case we have to set:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{ID\PYGZus{}Range} \PYG{o}{=} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{1} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Scattering\_Mechanism(channels)}] \leavevmode
-This optional array defines the scattering mechanism involved in
-each lidar channel. In particular the following values are adopted:
-
-\begin{tabulary}{\linewidth}{|L|L|}
-\hline
-
-0
- &
-$\rightarrow$ Total elastic backscatter
-\\\hline
-
-1
- &
-$\rightarrow$ $N_2$ vibrational Raman backscatter
-\\\hline
-
-2
- &
-$\rightarrow$ Cross polarization elastic backscatter
-\\\hline
-
-3
- &
-$\rightarrow$ Parallel polarization elastic backscatter
-\\\hline
-
-4
- &
-$\rightarrow$ $H_2O$ vibrational Raman backscatter
-\\\hline
-
-5
- &
-$\rightarrow$ Rotational Raman Stokes line close to elastic line
-\\\hline
-
-6
- &
-$\rightarrow$ Rotational Raman Stokes line far from elastic line
-\\\hline
-
-7
- &
-$\rightarrow$ Rotational Raman anti-Stokes line close to elastic line
-\\\hline
-
-8
- &
-$\rightarrow$ Rotational Raman anti-Stokes line far from elastic line
-\\\hline
-
-9
- &
-$\rightarrow$ Rotational Raman Stokes and anti-Stokes lines close to elastic line
-\\\hline
-
-10
- &
-$\rightarrow$ Rotational Raman Stokes and anti-Stokes lines far from elastic line
-\\\hline
-\end{tabulary}
-
-
-This information can be also taken from SCC\_DB. In our example we have:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Scattering\PYGZus{}Mechanism} \PYG{o}{=} \PYG{l+m+mi}{0}\PYG{p}{,} \PYG{l+m+mi}{2}\PYG{p}{,} \PYG{l+m+mi}{3}\PYG{p}{,} \PYG{l+m+mi}{1} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Acquisition\_Mode(channels)}] \leavevmode
-This optional array defines the acquisition mode (analog or
-photoncounting) involved in each lidar channel. In particular a value
-of 0 means analog mode and 1 photoncounting mode. This information
-can be also taken from SCC\_DB. In our example we have:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Acquisition\PYGZus{}Mode} \PYG{o}{=} \PYG{l+m+mi}{0}\PYG{p}{,} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{1} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Laser\_Repetition\_Rate(channels)}] \leavevmode
-This optional array defines the repetition rate in Hz used to
-acquire each lidar channel. This information can be also taken from
-SCC\_DB. In our example we are supposing we have only one laser with
-a repetition rate of 50 Hz so we have to set:

-\item[{Dead\_Time(channels)}] \leavevmode
-This optional array defines the dead time in ns associated to each
-lidar channel. The SCC will use the values given by this array to
-correct the photoncounting signals for dead time. Of course for
-analog signals no dead time correction will be applied (for analog
-channels the corresponding dead time values have to be set to
-undefined value). This information can be also taken from SCC\_DB. In
-our example the 1064 nm channel is acquired in analog mode so the
-corresponding dead time value has to be undefined. If we suppose a
-dead time of 10 ns for all other channels we have to set:
-
-\begin{Verbatim}[commandchars=\\\{\}]

-
-\item[{Dead\_Time\_Corr\_Type(channels}] \leavevmode
-This optional array defines which kind of dead time correction has
-to be applied on each photoncounting channel. The SCC will correct
-the data supposing a not-paralyzable channel if a value of 0 is found
-while a paralyzable channel is supposed if a value of 1 is found. Of
-course for analog signals no dead time correction will be applied and
-so the corresponding values have to be set to undefined value. This
-information can be also taken from SCC\_DB. In our example the 1064
-nm channel is acquired in analog mode so the corresponding has to be
-undefined. If we want to consider all the photoncounting signals as
-not-paralyzable ones: we have to set:
-

-\item[{Trigger\_Delay(channels)}] \leavevmode
-This optional array defines the delay (in ns) of the middle of the
-first rangebin with respect to the output laser pulse for each lidar
-channel. The SCC will use the values given by this array to correct
-for trigger delay. This information can be also taken from SCC\_DB.
-Let’s suppose that in our example all the photoncounting channels are
-not affected by this delay and only the analog channel at 1064nm is
-acquired with a delay of 50ns. In this case we have to set:

-\item[{Background\_Mode(channels}] \leavevmode
-This optional array defines how the atmospheric background has to be

-calculation of atmospheric background:
-\begin{enumerate}
-\item {}
-Average in the far field of lidar channel. In this case the value
-of this variable has to be 1
-
-\item {}
-Average within pre-trigger bins. In this case the value of this
-variable has to be 0
-
-\end{enumerate}
-
-This information can be also taken from SCC\_DB. Let’s suppose in our
-example we use the pre-trigger for the 1064nm channel and the far
-field for all other channels. In this case we have to set:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Background\PYGZus{}Mode} \PYG{o}{=} \PYG{l+m+mi}{0}\PYG{p}{,} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{1}\PYG{p}{,} \PYG{l+m+mi}{1} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{Background\_Low(channels)}] \leavevmode
-This mandatory array defines the minimum altitude (in meters) to
-consider in calculating the atmospheric background for each channel.
-In case pre-trigger mode is used the corresponding value has to be
-set to the rangebin to be used as lower limit (within pre-trigger
-region) for background calculation. In our example, if we want to
-calculate the background between 30000 and 50000 meters for all
-photoncounting channels and we want to use the first 500 pre-trigger
-bins for the background calculation for the 1064nm channel we have to
-set:

-\end{Verbatim}
-
-\item[{Background\_High(channels)}] \leavevmode
-This mandatory array defines the maximum altitude (in meters) to
-consider in calculating the atmospheric background for each channel.
-In case pre-trigger mode is used the corresponding value has to be
-set to the rangebin to be used as upper limit (within pre-trigger
-region) for background calculation. In our example, if we want to
-calculate the background between 30000 and 50000 meters for all
-photoncounting channels and we want to use the first 500 pre-trigger
-bins for the background calculation for the 1064nm channel we have to

-\item[{Molecular\_Calc}] \leavevmode
-This mandatory variable defines the way used by SCC to calculate the
-molecular density profile. At the moment two options are available:
-\begin{enumerate}
-\item {}
-US Standard Atmosphere 1976. In this case the value of this
-variable has to be 0
-
-\item {}
-Radiosounding. In this case the value of this variable has to be 1
-
-\end{enumerate}
-
-If we decide to use the option 1. we have to provide also the
-measured pressure and temperature at lidar station level. Indeed if
-we decide to use the option 2. a radiosounding file has to be
-submitted separately in NetCDF format (the structure of this file is
-summarized in table tab:sounding). Let’s suppose we want to use the
-option 1. so:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Molecular\PYGZus{}Calc} \PYG{o}{=} \PYG{l+m+mi}{0} \PYG{p}{;}
-\end{Verbatim}

-\item[{Pressure\_at\_Lidar\_Station}] \leavevmode
-Because we have chosen the US Standard Atmosphere for calculation of
-the molecular density profile we have to give the pressure in hPa at
-lidar station level:

-
-\item[{Temperature\_at\_Lidar\_Station}] \leavevmode
-Because we have chosen the US Standard Atmosphere for calculation of

-\end{Verbatim}
-
-\item[{Depolarization\_Factor(channels)}] \leavevmode
-This array is required only for lidar systems that use the two
-depolarization channels for the backscatter retrieval. It represents
-the factor $f$ to calculate the total backscatter signal
-$S_t$ combining its cross $S_c$ and parallel
-$S_p$ components: $S_t=S_p+fS_c$. This factor is
-mandatory only for systems acquiring $S_c$ and $S_p$
-and not $S_t$. For systems acquiring $S_c$,
-$S_p$ and $S_t$ this factor is optional and it will
-be used only for depolarizaton ratio calculation. Moreover only the
-values of the array corresponding to cross polarization channels will
-be considered; all other values will be not taken into account and
-should be set to undefined value. In our example for the wavelength
-532nm we have only the cross and the parallel components and not the
-total one. So we have to give the value of this factor only in
-correspondence of the 532nm cross polarization channel that
-corresponds to the channel index 1. Suppose that this factor is 0.88.
-Moreover, because we don’t have any other depolarization channels we
-have also to set all other values of the array to undefined value.

-
-\item[{LR\_Input(channels)}] \leavevmode
-This array is required only for lidar channels for which elastic
-backscatter retrieval has to be performed. It defines the lidar ratio
-to be used within this retrieval. Two options are available:
-\begin{enumerate}
-\item {}
-The user can submit a lidar ratio profile. In this case the value
-of this variable has to be 0.
-
-\item {}
-A fixed value of lidar ratio can be used. In this case the value
-of this variable has to be 1.
-
-\end{enumerate}
-
-If we decide to use the option 1. a lidar ratio file has to be
-submitted separately in NetCDF format (the structure of this file is
-summarized in table tab:lr). If we decide to use the option 2. the
-fixed value of lidar ratio will be taken from SCC\_DB. In our example
-we have to give a value of this array only for the 1064nm lidar
-channel because for the 532nm we will be able to retrieve a Raman
-backscatter coefficient. In case we want to use the fixed value
-stored in SCC\_DB we have to set:

-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{LR\PYGZus{}Input} \PYG{o}{=} \PYG{l+m+mi}{1}\PYG{p}{,}\PYG{n}{\PYGZus{}}\PYG{p}{,}\PYG{n}{\PYGZus{}}\PYG{p}{,}\PYG{n}{\PYGZus{}} \PYG{p}{;}
-\end{Verbatim}
-
-\item[{DAQ\_Range(channels)}] \leavevmode
-This array is required only if one or more lidar signals are
-acquired in analog mode. It gives the analog scale in mV used to
-acquire the analog signals. In our example we have only the 1064nm
-channel acquired in analog mode. If we have used a 100mV analog scale
-to acquire this channel we have to set:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{DAQ\PYGZus{}Range} \PYG{o}{=} \PYG{l+m+mi}{100}\PYG{p}{,}\PYG{n}{\PYGZus{}}\PYG{p}{,}\PYG{n}{\PYGZus{}}\PYG{p}{,}\PYG{n}{\PYGZus{}} \PYG{p}{;}

-This example file contains the minimum collection of mandatory
-information that has to be found within the Raw Lidar Data input
-file. If it is really necessary, the user can decide to add to these
-mandatory parameters any number of additional parameters considered in
-the previous example.
-
-Finally, suppose we want to make the following changes with respect to
-the previous example:
-\begin{enumerate}
-\item {}
-use a sounding file for molecular density calculation instead of “US
-Standar Atmosphere 1976”
-
-\item {}
-supply a lidar ratio profile to use in elastic backscatter retrieval
-instead of a fixed value
-
-\item {}
-provide a overlap function for overlap correction
-
-\end{enumerate}
-
-In this case we have to generate the following NetCDF additional files:
-\begin{description}
-\item[{rs\_20090130cc00.nc}] \leavevmode
-The name of Sounding Data file has to be computed as follows:
-\code{"rs\_"{}`{}`+{}`{}`Measurement\_ID}
-The structure of this file is summarized in table tab:sounding.
-
-\item[{ov\_20090130cc00.nc}] \leavevmode
-The name of Overlap file has to be computed as follows:
-\code{"ov\_"{}`{}`+{}`{}`Measurement\_ID}
-The structure of this file is summarized in table tab:overlap.
-
-\item[{lr\_20090130cc00.nc}] \leavevmode
-The name of Lidar Ratio file has to be computed as follows:
-\code{"lr\_"{}`{}`+{}`{}`Measurement\_ID}
-The structure of this file is summarized in table tab:lr.
-
-\end{description}
-
-Moreover we need to apply the following changes to the Raw Lidar Data
-input file:
-\begin{enumerate}
-\item {}
-Change the value of the variable \code{Molecular\_Calc} as follows:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Molecular\PYGZus{}Calc} \PYG{o}{=} \PYG{l+m+mi}{1} \PYG{p}{;}
-\end{Verbatim}
-
-Of course the variables \code{Pressure\_at\_Lidar\_Station} and
-\code{Temperature\_at\_Lidar\_Station} are not necessary anymore.
-
-\item {}
-Change the values of the array \code{LR\_Input} as follows:
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{LR\PYGZus{}Input} \PYG{o}{=} \PYG{l+m+mi}{0}\PYG{p}{,}\PYG{n}{\PYGZus{}}\PYG{p}{,}\PYG{n}{\PYGZus{}}\PYG{p}{,}\PYG{n}{\PYGZus{}} \PYG{p}{;}
-\end{Verbatim}
-
-\item {}
-Add the global attribute \code{Sounding\_File\_Name}
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Sounding\PYGZus{}File\PYGZus{}Name} \PYG{o}{=} \PYG{l+s}{"}\PYG{l+s}{rs\PYGZus{}20090130cc00.nc}\PYG{l+s}{"} \PYG{p}{;}
-\end{Verbatim}
-
-\end{enumerate}
-\begin{enumerate}
-\setcounter{enumi}{4}
-\item {}
-Add the global attribute \code{LR\_File\_Name}
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{LR\PYGZus{}File\PYGZus{}Name} \PYG{o}{=} \PYG{l+s}{"}\PYG{l+s}{lr\PYGZus{}20090130cc00.nc}\PYG{l+s}{"} \PYG{p}{;}
-\end{Verbatim}
-
-\item {}
-Add the global attribute \code{Overlap\_File\_Name}
-
-\begin{Verbatim}[commandchars=\\\{\}]
-\PYG{n}{Overlap\PYGZus{}File\PYGZus{}Name} \PYG{o}{=} \PYG{l+s}{"}\PYG{l+s}{ov\PYGZus{}20090130cc00.nc}\PYG{l+s}{"} \PYG{p}{;}
