Land/Water Masking

• Why would I want to do this?
• make_master_mask This script generates a master land/ water mask for use in the following two programs.
• do_masking This script takes the master mask generated using make_master_mask, and extracts the AVHRR band 4 and band 5 data
• mask_subThis script generates a land/water mask, extracts AVHRR band 4 and 5 data, and exports a cloud region in ascii format for importing into RADIANNET

Geostationay Processing

• ncar_goes_proc: Remaps GOES data from our NCAR source, and does thermal band subtraction.
• ncar_goes_rast: Remaps GOES data from our NCAR source, does thermal band subtraction, and injects coastlines, temperature scale, legend, etc., and outputs them as a sunraster
• gms_proc: Remaps GMS data from Hawaii site, and does thermal band subtraction.

• hirs_proc: Uses AVHRR and HIRS data from the same satellite swath, masks out bad data strips (calibration lines) from the HIRS data, and masks out the area of the volcanic cloud from the HIRS data using the AVHRR band 4-5 technique.
