8 The Single Calculus Chain (SCC) is the standard EARLINET tool to perform |
|
9 automatic and quality nchecked analysis of raw lidar data. It is |
|
10 composed by three different modules: |
|
11 |
|
12 - ELPP (EARLINET Lidar Pre-Processor) |
|
13 - ELDA (EARLINET Lidar Data Analizer) |
|
14 - ELDEC (EARLINET Lidar DEpolarization Calibrator) |
|
15 |
|
16 Whenever an input file containing raw lidar data has been submitted to |
|
17 the SCC ELPP is automatically ran on it. The ELPP module pre-processes |
|
18 the raw data performing all the corrections and data handling needed |
|
19 before the optical retrieval algorithms can be applied by ELDA module. |
|
20 The ELPP output files contain pre-processed range corrected signals |
|
21 corrected for instrumental effects as well as atmospheric molecular |
|
22 parameters calculated from standard model or radiosounding. Typically, |
|
23 the vertical and temporal resolutions of the pre-processed signals |
|
24 included in these files is lower than the raw vertical and temporal |
|
25 resolution as in general time/vertical integration is performed by ELPP |
|
26 to increase the SNR and allow the calculation of optical products with a |
|
27 reduced uncertainties. As a consequence the ELPP output files are called |
|
28 Low Resolution SCC L1 Products. Another SCC module (HiRELPP – High |
|
29 Resolution EARLINET Lidar Pre-Processor) currently under development |
|
30 will produce High Resolution SCC L1 Products in which both time and |
|
31 vertical resolution are kept as higher as possible. |
|
32 |
|
33 This document provides a detailed description about the structure and |
|
34 the format of Low Resolution SCC L1 Product as produced by the SCC v4.0. |

|
37 :name: low-resolution-scc-l1-product-file-format |
|
38 |
|
39 The Low Resolution SCC L1 Products are files in Network Common Data Form |
|
40 (NetCDF) which is a well known self-describing, machine-independent data |
|
41 format that support the creation, access, and sharing of array-oriented |
|
42 scientific data. For more information about NetCDF format: |
|
43 http://www.unidata.ucar.edu/software/netcdf/. |
|
44 |
|
45 The NetCDF is a binary format that allows the definition of |
|
46 multi-dimensional variables of several types (integers, double, |
|
47 character, etc). For each variable it is possible to define one or more |
|
48 attributes where to specify variable properties like units, long name, |
|
49 description, etc. |
|
50 |
|
51 It is possible to define global attributes which are not related to a |
|
52 specific variable but to the whole file. |
|
53 |
|
54 A NetCDF file is composed by four different section: |
|
55 |
|
56 - dimensions |
|
57 |
|
58 this section contains all the dimensions used in the definition of |
|
59 all the variables included in the NetCDF file |
|
60 |
|
61 - variables |
|
62 |
|
63 this section contains all the variables stored in the NetCDF file. |
|
64 Each variable is defined as a multi-dimensional array of a specific |
|
65 type and with all the dimensions defined in the dimensions section |
|
66 |
|
67 global attributes |
|
68 |
|
69 this section lists all the attributes referring to the whole file. As |
|
70 the variable the attributes (global or the one attached to a specific |
|
71 variable) can be of different type |
|
72 |
|
73 - data |
|
74 |
|
75 in this section the data contained in each variable defined in |
|
76 variable section is stored. Attribute values (both global or related |
|
77 to a specific variable) are not reported in data section but directly |
|
78 in variable or global attribute sections. |
|
79 |
|
80 Each Low Resolution SCC L1 Product correspond to a single emission |
|
81 wavelength. For example it is possible to find in the same file the |
|
82 elastic and the Raman channel pre-processed time-series corresponding to |
|
83 the same emission wavelength (but to a different detection wavelengths) |
|
84 but not two elastic time-series referring to different emission |
|
85 wavelengths. |

92 The following dimensions are defined in the Low Resolution SCC L1 |
|
93 Product: |

|
100 The dimension *time* specifies the number of RCS (for each channel) |

103 The dimension *points* represents the number of rangebins characterizing |
|
104 the pre-processed RCS. In case RCSs corresponding to different channels |
|
105 are characterized by different rangebins the dimension time is to the |
|
106 the maximum value of rangebins. |
|
107 |
|
108 The dimension *channels* indicates the number channels at which the RCS |
|
109 time-series included in the file refer to. |
|
110 |
|
111 The dimension *scan\_angles* takes into account how many zenith scan |
|
112 angles have been used to measure the RCS time-series reported into the |
|
113 file |

|
1958 :name: low-resolution-scc-l1-product-filename |
|
1959 |
|
1960 The filename of the Low Resolution SCC L1 Products has the following |
|
1961 format: |
|
1962 |
|
1963 measurementid\_prodid.nc |
|
1964 |
|
1965 The *measurementid* is a 12 characters alphanumeric string identifying |
|
1966 the measurement session at which the product refers to. The |
|
1967 *measurementid* (which is unique for a given measurement session) allows |
|
1968 to fully trance the SCC analysis performed on the current product. This |
|
1969 can be done because each measurement session is recorded in a SCC |
|
1970 database using the same string. In the same database the measurement |
|
1971 session is linked to the lidar configuration used to analyze the data |
|
1972 (which is recorded and fully characterized in the SCC database providing |
|
1973 all the channel details) and to a set of optical products to calculate. |
|
1974 |
|
1975 The *prodid* is a numeric string identifying the optical product that |
|
1976 has to be calculated by SCC (in particular ELDA module) by applying the |
|
1977 optical retrieval algorithm on the current pre-processed L1 product. |
|
1978 |
|
1979 Different product types are defined within the SCC. The contents of a |
|
1980 Low Resolution SCC L1 product depends on the type of the product |
|
1981 specified in the its filename by prodid string. In particular only the |
|
1982 **Aerosol Related Variables **\ and\ ** Polarization related variables** |
|
1983 specified in the section 2.2 can change depending on product type. In |
|
1984 Tab. 3.1 are reported the product-type related variables for each |
|
1985 optical product type. |
|
1986 |
|
1987 To link the *prodid* string with the corresponding product type the SCC |
|
1988 database a proper query to the SCC database should be addressed. |
