A new bit trim mask has been delivered to mitigate overloading the HRD stream limit of 15 mbps. This 24-hour full spectrum test will be conducted to validate the new bit trim mask.

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.  A new bit trim mask has been delivered to mitigate overloading the HRD stream limit of 15 mbps.  This 24-hour full spectrum test will be conducted to validate the new bit trim mask.  For the duration of the test CrIS will be removed out of HRD to prevent losing any mission data due to MDF overflow.  The CrIS cal/val team will evaluate the performance of the revised full spectrum bit trim mask through-out the test.
