rad_corr_reg_coef_17boxcar_airsv10ab_2.asc VIIRS collocation LUT Files The CrIS-VIIRS collocation code uses a set of look up tables to more quickly collocate the two instruments. These files are called: CrIS_VIIRS_MOD.dat CrIS_VIIRS_MOD_HEI.dat CrIS_VIIRS_WGT.dat CrIS_VIIRS_WGT_HEI.dat Template Files The system uses a number of template files. These are all static files that will only change with a new delivery of the system. They are never modified by the scripts and programs that use them. Scripts will only copy these files to a local directory or create soft links to them CDL Template These are template parameter files used for generating the NUCAPS SDR and NUCAPS EDR granule subsets. These files contain the lists of channels and footprints to be extracted for each type of subset. They also contain the variable lists, array sizes and array dimensions for each NetCDF output file. Each file can be converted into a NetCDF file using the ncgen NetCDF4 library utility. This file will have a complete header based on that of the CDL template, but contains no instrument data values, only fill (missing) values. These files are then populated with instrument data values by the subsetter code. There is a different template file for each type of subset. The following NUCAPS CDL template files shown in Table 22 are present in the current build: Table NUCAPS CDL Files CDL Template Name Description nucaps_all.cdl A template for all fovs, 1317 channels (4 scans) nucaps_c0300_allfovs.cdl A template for all fovs, 399 channels (4 scans)
