satpy.readers.amsr2_l2_gaasp module
GCOM-W1 AMSR2 Level 2 files from the GAASP software.
GAASP output files are in the NetCDF4 format. Software is provided by NOAA and is also distributed by the CSPP group. More information on the products supported by this reader can be found here: https://www.star.nesdis.noaa.gov/jpss/gcom.php for more information.
GAASP includes both swath/granule products and gridded products. Swath products are provided in files with “MBT”, “OCEAN”, “SNOW”, or “SOIL” in the filename. Gridded products are in files with “SEAICE-SH” or “SEAICE-NH” in the filename where SH stands for South Hemisphere and NH stands for North Hemisphere. These gridded products are on the EASE2 North pole and South pole grids. See https://nsidc.org/ease/ease-grid-projection-gt for more details.
Note that since SEAICE products can be on both the northern or southern hemisphere or both depending on what files are provided to Satpy, this reader appends a _NH and _SH suffix to all variable names that are dynamically discovered from the provided files.
