Description-en: Python package to read and calibrate NOAA AVHRR GAC data
pygac reads NOAA AVHRR Global Area Coverage (GAC) data, and performs
state of the art calibration and navigation.
.
It must be noted that pygac expects Level 1b file to contain normal
GAC header and data records, the format of which are mentioned in the
official NOAA POD and KLM Data User Guides.
The user should not prepend any other header (e.g. when downloading
GAC data from CLASS archive etc) to the L1b file.
In the first pre-processing step, pygac determines whether the GAC
data comes from the second (i.e. NOAA-14 and before) or the third
generation (NOAA-15 and onwards) AVHRR instrument by "pygac-run".
This is done by reading the first three bytes of the data set.
If they contain the any of the following values, ["CMS", "NSS", "UKM",
"DSS"], then the KLM reader from "gac_klm.py" file is invoked,
otherwise the POD reader is invoked (gac_pod.py).
