Subject: TRMM data for January 10, 2000



Dear TRMM Science Users;

TSDIS has been informed the TRMM MOC experienced a hardware failure of
it's Programmable Telemetry Processor-1 (failed hard drive), which
ultimately resulted in several minutes of lost science data capture
due to temporary recorder overflows on the spacecraft starting at
00-010/07:25:46z. The overflow durations are as follows:

	LIS       8 min 19 sec
	PR        6 min 50 sec 
	TMI       6 min 53 sec
	VIRS     13 min 3 sec

This problem did not significantly impact the TRMM data products
produced for Janaury 10, 2000 (2000:010). Partial granules have been
produced for the data gaps (orbit #12196). TSDIS Science Group has
validated the data produced, and stated the 1A21 product will be
slightly smaller than usual.  

Please contact the helpdesk if you have any questions.

Thank you,
