After an instrument anomaly on May 29, 2009 the TRMM PR resumed
observations on June 17th, 2009. All TRMM PR production data
is currently being held until a calibration effort is completed by
JAXA. Our intention was to be able to release the calibrated,
post-anomaly PR data by the end of Sept. 2009 but that has not
been possible.
