1.5.1.1.7.1.3. polar2grid.readers.abi_l2_nc module

The ABI Level 2 Reader operates on NOAA Level 2 (L2) NetCDF files from the GOES-16 (GOES-East), GOES-17/18 (GOES-West) Advanced Baseline Imager (ABI) instrument. The ABI L2 NetCDF reader works off of the input filenames to determine if a file is supported by Geo2Grid. Files usually have the following naming scheme:

OR_ABI-L2-{PROD}F-M3_G{SAT}_s20182531700311_e20182531711090_c20182531711149.nc

and:

CG_ABI-L2-{PROD}F-M6_G{SAT}_s20223271830316_e20223271839394_c20223271842100.nc

These are the mission compliant file naming conventions used by the NOAA Comprehensive Large Array-data Stewardship System (CLASS) archive and the CSPP Geo AIT Framework Level 2 software. The ABI L2 NetCDF reader supports most L2 products, but Geo2Grid is tested with a limited subset of these. See the table below for more information. The ABI L2 NetCDF reader can be provided to the main geo2grid.sh script using the -r option and the reader name abi_l2_nc.
