1.5.1.1.7.1.19. polar2grid.readers.modis_l2 module

The MODIS L2 Reader operates on HDF4 Level 2 files from the MODIS instrument.

These files are created from Level 1b data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on the Aqua and Terra satellites. The reader is designed to work with files created by the IMAPP direct broadcast processing system (file naming conventions such as a1.17006.1855.mod35.hdf), but can support other types of L2 files, including the NASA archived files (file naming conventions such as MOD35_L2.A2017004.1732.005.2017023210017.hdf). The reader can be specified to the polar2grid.sh script by using the reader name modis_l2.

It provides the following products:

Product Name	Description
cloud_mask	Cloud Mask
land_sea_mask	Land Sea Mask
snow_ice_mask	Snow Ice Mask
sst	Sea Surface Temperature
lst	Land Surface Temperature
ndvi	Normalized Difference Vegetation Index
ist	Ice Surface Temperature
inversion_strength	Inversion Strength
inversion_depth	Inversion Depth
ice_concentration	Ice Concentration
ctt	Cloud Top Temperature
tpw	Total Precipitable Water
