1.5.1.1.7.1.21. polar2grid.readers.viirs_edr module¶
The VIIRS EDR Reader operates on Environmental Data Record (SDR) HDF5 files from the Suomi National Polar-orbiting Partnership’s (NPP), the NOAA20, or the NOAA-21 Visible/Infrared Imager Radiometer Suite (VIIRS) instrument. The VIIRS EDR reader requires filenames to match one of a couple different standard filename schemes used for official products. EDR files are typically named as below:
JRR-AOD_v3r2_npp_s202307230941369_e202307230943011_c202307231038217.nc
The VIIRS EDR reader supports most JPSS Risk Reduction (JRR) enterprise algorithm
output. The VIIRS EDR reader can be specified to the polar2grid.sh
script
with the reader name viirs_edr
.
This reader’s default remapping algorithm is ewa
for Elliptical Weighted
Averaging resampling. The --weight-delta-max
parameter set to 40 and the
--weight-distance-max
parameter set to 2.
