On Tuesday April 18, 2023 at 12:00 UTC the GPM Flight Operations Team will be uploading a firmware update to the GPM satellite. During this time the instruments will be shut down and the spacecraft will be put into sun acquisition mode. No science data will be available until the spacecraft is commanded back into Mission Science Mode. Instruments are expected to be back to nominal operations by 20:00 UTC. It will take additional time for PPS production to ingest and verify the data before processing restart. We will provide an update when activities are complete and nominal production has resumed. 

The IMERG Early and Late products will continue to be produced during this period without input from the GPM GMI instrument. 

We appreciate your patience and understanding during this period.

If you have any concerns, comments or questions, please contact us.
