ulalume3@99: Low Resolution SCC L1 Products ulalume3@99: ============================== ulalume3@99: ulalume3@99: .. warning:: ulalume3@99: This section is still under development. ulalume3@99: ulalume3@99: ulalume3@99: Introduction ulalume3@99: ------------ ulalume3@99: ulalume3@99: The Single Calculus Chain (SCC) is the standard EARLINET tool to perform ulalume3@99: automatic and quality nchecked analysis of raw lidar data. It is ulalume3@99: composed by three different modules: ulalume3@99: ulalume3@99: - ELPP (EARLINET Lidar Pre-Processor) ulalume3@99: - ELDA (EARLINET Lidar Data Analizer) ulalume3@99: - ELDEC (EARLINET Lidar DEpolarization Calibrator) ulalume3@99: ulalume3@99: Whenever an input file containing raw lidar data has been submitted to ulalume3@99: the SCC ELPP is automatically ran on it. The ELPP module pre-processes ulalume3@99: the raw data performing all the corrections and data handling needed ulalume3@99: before the optical retrieval algorithms can be applied by ELDA module. ulalume3@99: The ELPP output files contain pre-processed range corrected signals ulalume3@99: corrected for instrumental effects as well as atmospheric molecular ulalume3@99: parameters calculated from standard model or radiosounding. Typically, ulalume3@99: the vertical and temporal resolutions of the pre-processed signals ulalume3@99: included in these files is lower than the raw vertical and temporal ulalume3@99: resolution as in general time/vertical integration is performed by ELPP ulalume3@99: to increase the SNR and allow the calculation of optical products with a ulalume3@99: reduced uncertainties. As a consequence the ELPP output files are called ulalume3@99: Low Resolution SCC L1 Products. Another SCC module (HiRELPP – High ulalume3@99: Resolution EARLINET Lidar Pre-Processor) currently under development ulalume3@99: will produce High Resolution SCC L1 Products in which both time and ulalume3@99: vertical resolution are kept as higher as possible. ulalume3@99: ulalume3@99: This document provides a detailed description about the structure and ulalume3@99: the format of Low Resolution SCC L1 Product as produced by the SCC v4.0. ulalume3@99: ulalume3@99: Low Resolution SCC L1 Product: File format ulalume3@99: ------------------------------------------ ulalume3@99: ulalume3@99: The Low Resolution SCC L1 Products are files in Network Common Data Form ulalume3@99: (NetCDF) which is a well known self-describing, machine-independent data ulalume3@99: format that support the creation, access, and sharing of array-oriented ulalume3@99: scientific data. For more information about NetCDF format: ulalume3@99: http://www.unidata.ucar.edu/software/netcdf/. ulalume3@99: ulalume3@99: The NetCDF is a binary format that allows the definition of ulalume3@99: multi-dimensional variables of several types (integers, double, ulalume3@99: character, etc). For each variable it is possible to define one or more ulalume3@99: attributes where to specify variable properties like units, long name, ulalume3@99: description, etc. ulalume3@99: ulalume3@99: It is possible to define global attributes which are not related to a ulalume3@99: specific variable but to the whole file. ulalume3@99: ulalume3@99: A NetCDF file is composed by four different section: ulalume3@99: ulalume3@99: - dimensions ulalume3@99: ulalume3@99: this section contains all the dimensions used in the definition of ulalume3@99: all the variables included in the NetCDF file ulalume3@99: ulalume3@99: - variables ulalume3@99: ulalume3@99: this section contains all the variables stored in the NetCDF file. ulalume3@99: Each variable is defined as a multi-dimensional array of a specific ulalume3@99: type and with all the dimensions defined in the dimensions section ulalume3@99: ulalume3@99: global attributes ulalume3@99: ulalume3@99: this section lists all the attributes referring to the whole file. As ulalume3@99: the variable the attributes (global or the one attached to a specific ulalume3@99: variable) can be of different type ulalume3@99: ulalume3@99: - data ulalume3@99: ulalume3@99: in this section the data contained in each variable defined in ulalume3@99: variable section is stored. Attribute values (both global or related ulalume3@99: to a specific variable) are not reported in data section but directly ulalume3@99: in variable or global attribute sections. ulalume3@99: ulalume3@99: Each Low Resolution SCC L1 Product correspond to a single emission ulalume3@99: wavelength. For example it is possible to find in the same file the ulalume3@99: elastic and the Raman channel pre-processed time-series corresponding to ulalume3@99: the same emission wavelength (but to a different detection wavelengths) ulalume3@99: but not two elastic time-series referring to different emission ulalume3@99: wavelengths. ulalume3@99: ulalume3@99: Low Resolution SCC L1 Product Format: dimensions ulalume3@99: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ulalume3@99: ulalume3@99: The following dimensions are defined in the Low Resolution SCC L1 ulalume3@99: Product: ulalume3@99: ulalume3@99: - time ulalume3@99: - points ulalume3@99: - channels ulalume3@99: - scan\_angles ulalume3@99: ulalume3@99: The dimension *time* specifies the number of RCS (for each channel) ulalume3@99: composing all the pre-processed time-series reported in the file. ulalume3@99: ulalume3@99: The dimension *points* represents the number of rangebins characterizing ulalume3@99: the pre-processed RCS.

The ulalume3@99: *measurementid* (which is unique for a given measurement session) allows ulalume3@99: to fully trance the SCC analysis performed on the current product. This ulalume3@99: can be done because each measurement session is recorded in a SCC ulalume3@99: database using the same string. In the same database the measurement ulalume3@99: session is linked to the lidar configuration used to analyze the data ulalume3@99: (which is recorded and fully characterized in the SCC database providing ulalume3@99: all the channel details) and to a set of optical products to calculate. ulalume3@99: ulalume3@99: The *prodid* is a numeric string identifying the optical product that ulalume3@99: has to be calculated by SCC (in particular ELDA module) by applying the ulalume3@99: optical retrieval algorithm on the current pre-processed L1 product. ulalume3@99: ulalume3@99: Different product types are defined within the SCC. The contents of a ulalume3@99: Low Resolution SCC L1 product depends on the type of the product ulalume3@99: specified in the its filename by prodid string. In particular only the ulalume3@99: **Aerosol Related Variables **\ and\ ** Polarization related variables** ulalume3@99: specified in the section 2.2 can change depending on product type. In ulalume3@99: Tab. 3.1 are reported the product-type related variables for each ulalume3@99: optical product type. ulalume3@99: ulalume3@99: To link the *prodid* string with the corresponding product type the SCC ulalume3@99: database a proper query to the SCC database should be addressed. ulalume3@99: ulalume3@99: **Table 3.1:** Possible variables that can be found in the SCC L1 ulalume3@99: Products for each optical product type ulalume3@99: ulalume3@99: +--------------------------------------------------------------+---------------------------------------------------+ ulalume3@99: | Product type | Possible variables in Low Resolution L1 Product | ulalume3@99: +--------------------------------------------------------------+---------------------------------------------------+ ulalume3@99: | Extinction only | vrRN2, vrRN2nr, vrRN2fr | ulalume3@99: | | | ulalume3@99: | | vrRN2\_err, vrRN2nr\_err, vrRN2fr\_err | ulalume3@99: +--------------------------------------------------------------+---------------------------------------------------+ ulalume3@99: | Elastic Backscatter | elT, elTnr, elTfr | ulalume3@99: | | | ulalume3@99: | Elastic Backscatter + Particle Linear Depolarization Ratio | elT\_err, elTnr\_err, elTfr\_err | ulalume3@99: | | | ulalume3@99: | | elPR, elPRnr, elPRfr | ulalume3@99: | | | ulalume3@99: | | elPR\_err, elPRnr\_err, elPRfr\_err | ulalume3@99: | | | ulalume3@99: | | elPT, elPTnr, elPTfr | ulalume3@99: | | | ulalume3@99: | | elPT\_err, elPTnr\_err, elPTfr\_err | ulalume3@99: +--------------------------------------------------------------+---------------------------------------------------+ ulalume3@99: | Raman Backscatter | elT, elTnr, elTfr | ulalume3@99: | | | ulalume3@99: | Raman Backscatter + Particle Linear Depolarization Ratio | elT\_err, elTnr\_err, elTfr\_err | ulalume3@99: | | | ulalume3@99: | Lidar Ratio | elPR, elPRnr, elPRfr | ulalume3@99: | | | ulalume3@99: | | elPR\_err, elPRnr\_err, elPRfr\_err | ulalume3@99: | | | ulalume3@99: | | elPT, elPTnr, elPTfr | ulalume3@99: | | | ulalume3@99: | | elPT\_err, elPTnr\_err, elPTfr\_err | ulalume3@99: | | | ulalume3@99: | | vrRN2, vrRN2nr, vrRN2fr | ulalume3@99: | | | ulalume3@99: | | vrRN2\_err, vrRN2nr\_err, vrRN2fr\_err | ulalume3@99: +--------------------------------------------------------------+---------------------------------------------------+
