4.15. AWS MWR Reader¶
The Arctic Weather Satellite-1 (AWS-1) MicroWave Radiometer (MWR) reader is for reading L1B files for the MWR instrument.
These files are NetCDF4 files. The reader can be specified with
the polar2grid.sh command using the aws1_mwr_l1b_nc reader name.
This reader’s default resampling algorithm is ewa for Elliptical Weighted
Averaging resampling. The --weight-delta-max option is set to 100 and
--weight-distance-max is set to 1.
The MWR reader provides the following products:
