This package contains sample readers for AIRS products in C and FORTRAN.
It is intended solely to show how AIRS data can be read, and is not a
supported AIRS product.

For each of these seven AIRS types, there are C & FORTRAN include files and
one-call readers that read an entire granule into memory. There are also
C sample programs that use the readers to extract a subset of the data.
