Description 2015-09-14T01:38:00Z
We have not received most of two orbits of Aqua MYDGBAD ephemeris data with the result that NRT L2 processing covering 2015-09-13 17:10 to 20:10z is on hold. There is also a gap in MYDGBAD between 2015-09-13 16:46:45 and 16:47:05z, and MYDGBAD granules between 16:45 and 17:20 appear to be slightly unde rsized which might effect the quality of downstream data.

Yesterday EDOS said "It looks like Aqua had some spacecraft and or ground station issues Sunday which resulted in EDOS receiving some very ratty data during the time period mentioned in your email." There has been no further word from EDOS and we are closing processing. Some additional d ata will be created, but the quality may be poor.

Aqua CDH Engineers explanation for the DOY 256 data loss:
Uncorrectables occurred during the beginning of a replay that was initiated to recover data from a previous event. This caused a data loss in Housekeeping, GBAD, AMSU-1, AMSU-2, CERES-F, CERES-A, AMSR-E, MODIS and AIRS data. The housekeeping data was recovered through S-Band playbacks. A data-loss report is forthcoming.

Return to all issues
