Topic: SNPP CrIS Full Spectrum Test

Date/Time Issued: August 27, 2013 17:40 UTC

Product(s) or Data Impacted: CrIS Science Data:

The test will span from 8/27 13:13z to 8/28 14:50z. Impacts of the test include:

CrIS data will be removed from HRD.
While in the full spectrum configuration the CrIS RDRs will increase in size
CrIS science data drop-out while switching between full spectrum and truncated configurations

Date/Time of Initial Impact: August 27, 2013 13:13:00 UTC

Date/Time of Expected End: August 28, 2013 14:50:00 UTC

Length of Outage: Approximately 1 Day, 1 Hour, and 37 Minutes.

Details/Specifics of Change: Currently, the Cross-track Infared Sounder (CrIS) performs onboard truncation of the interferograms that are sent down from the spacecraft for ground processing. A full spectrum test executed in March 2013 showed an overflow on the Mission Data Formatter (MDF) due to the increase of CrIS data to HRD.
