Terra MODIS Command Processor and Formatter Reset Anomaly - Updated

Mar 18, 2022

Terra MODIS encountered a Command Processor and Format Processor reset on March 15, 2022. As a result, Terra MODIS entered Standby mode. Though the data acquisition is going on, with some interruptions between 08:45z - 09:40z, the science quality will be degraded as onboard tables were reverted back to their at-launch values. The recovery process has been divided into two phases. The first part of the recovery process was completed on March 15 and Terra MODIS successfully transitioned to back to Science mode. The second part of the recovery process to upload additional patches and gain tables to return the same configuration as before the anomaly was performed on March 17. Over the next few days, radiometric performance will continue to be evaluated and any updates will be reported.

Update: All affected Terra MODIS Version 6 and 6.1 data products have been reprocessed as of April 15, 2022.
