Document - Technical Note

Draft-specification-of-ATSR-SADIST-2-products.pdf

This document is a draft specification of the scientific products from RAL's SADIST-2 ATSR data-processing software. Since SADIST-2 is being developed such that it can process data from both ATSR-1 and ATSR-2 instruments, the products described here have been designed to be sufficiently flexible and modular that they are equally valid for either instrument.
