1.5.1.1.7.1.9. polar2grid.readers.ami_l1b module

The AMI L1B Reader operates on Level 1B (L1B) NetCDF files for the Advanced Meteorological Imager (AMI) instrument on board the Korean Meteorological Administration (KMA) GEO-KOMPSAT-1 (GK-2A) satellite. Geo2Grid determines if it supports files based on the input filename. Files for AMI supported by Geo2Grid usually have the following naming scheme:

gk2a_ami_le1b_vi004_fd010ge_201909251200.nc

The AMI L1B reader supports all instrument spectral bands, identified in Geo2Grid as the products shown in the table below. The AMI L1B reader can be provided to the main geo2grid.sh script using the -r option and the reader name ami_l1b.

The list of supported products includes true and natural color imagery. These are created by means of a python based atmospheric Rayleigh scattering correction algorithm that is executed as part of the Geo2Grid AMI L1B reader, along with sharpening to the highest spatial resolution. For more information on the creation of RGBs, please see the RGB section.
