[ PR data loss and recovery ]
June 18, 2009

On May 29, 2009, the TRMM PR experienced a major anomaly, resulting in a loss of data. JAXA and NASA have inferred that a frequency converter and interface system unit might not be worked normally. JAXA and NASA were able to successfully switch those two units to the backup systems on June 17 and the PR became operational again. Note that this change could have some impact on the data.
JAXA and NASA will be examining the data over the next month or longer to determine what, if any, changes have occurred.
