| 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. | |
| 35 | |
| 36 1. .. rubric:: Low Resolution SCC L1 Product: File format | |
| 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. | |

| 90 :name: low-resolution-scc-l1-product-format-dimensions | |
| 91 | |
| 92 The following dimensions are defined in the Low Resolution SCC L1 | |
| 93 Product: | |
| 94 | |
| 95 - time | |
| 96 - points | |
| 97 - channels | |
| 98 - scan\_angles | |
| 99 | |
| 100 The dimension *time* specifies the number of RCS (for each channel) | |
| 101 composing all the pre-processed time-series reported in the file. | |
| 102 | |
| 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 | |
| 114 | |

| 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. | |
