Increased Latencies on GPM Products Due to TDRSS Safe Hold


On the afternoon of March 16, one of the TDRSS data relay satellites went into safe hold. This has reduced the relay satellites available for downloading the data from the GPM core satellite to the ground station at White Sands, NM.  It means that times between download contacts have increased.

No data is lost but data latency has been greatly affected for the GPM near-realtime core satellite products: GMI and DPR. We understand that this increase in latency will be the norm for the next couple of days.  There are NO issues with the GPM core satellite or its sensors. Also there are NO issues with the GPM ground system, data system, or network. 

When the TDRSS satellite situation is rectified the NRT latencies will return to normal.
