* Monitoring personnel noticed a drop in the number of accepted data for some channels in early June. The change occurred on June 17. The satellite messages and instrument noise levels were checked but there was no indication of what had caused the change. The accepted rate for some corresponding channels increased for the NCEP assimilation (per their monitoring plots). We are keeping an eye on this instrument. | * Monitoring personnel noticed a drop in the number of accepted data for some channels in early June. The change occurred on June 17.

== AQUA data outage == | |||
* On August 16, 2020 at 09:26:40 UTC, the data formatter for the solid state recorder on the Aqua satellite began exhibiting anomalous behavior during playback operations. All X-Band science data playback has been corrupted since the anomaly began. Spacecraft housekeeping data continues to be recorded and successfully transmitted to the ground. The other spacecraft bus subsystems and instruments are functioning nominally. Direct Broadcast (DB) data continues to transmit nominally. An update will be provided when the situation is resolved. | |||
== GPM satellite anomaly impacting core observatory data == | |||
Effective about 11 UTC 19 August 2020, the GPM Mission Operations Center (MOC) stopped receiving data from the satellite. While the satellite and the instruments are healthy, the Flight Operations Team (FOT) is working to safely reestablish nominal operations. Return to data collection mode may take days to a week, which will result in a permanent data gap in the GPM Radar and Radiometer products. IMERG Near Real-Time will continue to be produced but obviously no GMI data will be included in either the Early or Late product. | |||
