SPECIAL MESSAGE:  

This NOAA site will no longer provide GOES-East imagery. For access to high resolution GOES-East imagery from GOES-16, please go to the site: https://www.star.nesdis.noaa.gov/GOES/index.php. We apologize for the inconvenience and appreciate your patience.

GOES Sounder Spectral Response Functions

(Revised, August 2011)

Sounder spectral response functions (SRFs) for GOES-8 through GOES-15 are available for download below. The SRFs were provided by ITT, the instruments' manufacturer. The second column contains links to the currently operational SRFs. Information about the SRFs linked in the 3rd column is discussed below.

GOES-8 and GOES-10 Sounder SRF History

For GOES-8 and GOES-10 the "currently operational" SRFs were the ones used throughout the lifetimes of those sounders for operational processing of data products at NESDIS. The SRFs labeled "Updated on 9/28/98" were provided by ITT, and are believed to represent more accurately the true SRFs of those instruments. However, NESDIS did NOT use these updated SRFs in its operational product generation because the potential inconvenience and magnitude of effort required to do so would have outweighed the expected benefit of the small improvements that might have been realized in product performance. Nonetheless the updated SRFs are made available here to the user community.

GOES-14 Sounder SRF History

Two versions of the spectral response functions (SRFs) for the GOES-14 Sounder are presented on this website, along with the related calibration parameters associated with each SRF version. These different SRFs correspond to different releases of the Calibration and Alignment Handbook by the instrument vendor ITT.

Released RevD – Discontinued on August 09, 2011
These are the SRFs provided by the instrument vendor in Release 2005, Rev D. They have been used for all GOES 14 Sounder calibration processing before GOES-14 went into normal mode "storage" on January 19, 2010 (this includes processing of the GOES-14 Post Launch Test data and the NOAA Science Test data).

Released RevD – Discontinued on August 09, 2011
These are the SRFs provided by the instrument vendor in Release 2005, Rev D. They have been used for all GOES 14 Sounder calibration processing before GOES-14 went into normal mode "storage" on January 19, 2010 (this includes processing of the GOES-14 Post Launch Test data and the NOAA Science Test data).

Released RevF – Currently Operational
These are the SRFs most recently provided by the instrument vendor in Release 2010, Rev F. They have been used for GOES-14 Sounder calibration processing after August 9, 2011.

GOES-15 Sounder SRF History

Two versions of the spectral response functions (SRFs) for the GOES-15 Sounder are presented on this website, along with the related calibration parameters associated with each SRF version. These different SRFs correspond to different releases of the Calibration and Alignment Handbook by the instrument vendor ITT.

Released RevE – Discontinued on August 12, 2010
These are the SRFs provided by the instrument vendor in Release 2008, Rev E. They have been used for all GOES 15 Sounder calibration processing before August 12, 2010 (when GOES-15 was undergoing Post Launch Testing, but before the NOAA Science Tests).

Released RevF – Currently Operational
These are the SRFs most recently provided by the instrument vendor in Release 2010, Rev F. They have been used for all GOES 15 Sounder calibration processing after August 12, 2010 (including the very end of Post Launch Testing and including all of the NOAA Science Tests).
