GOES-8 through GOES-O Sounder Spectral Response Functions
(Revised, March 2009)
Sets of spectral response functions (SRFs) are available for the each of the sounders on GOES-8 through GOES-O.
These sets were provided by ITT, the instruments' manufacturer. The contents of the first set, "currently
operational," are the SRFs that have been used over the lifetimes of sounders for operational production of data
products at NESDIS. The second set, "updated," were provided by ITT more recently and are believed to represent
more accurately the true SRFs of the instruments. Currently, NESDIS does not plan to switch to the updated SRFs
in its processing, because we believe that the inconvenience and magnitude of the effort to do so outweighs the
expected benefit of the small improvements that might be realized in product performance. Nonetheless, the new
SRFs are being made available here to the user community.
