What happened to Oct 2014 TMPA data?

[GES DISC - ingridgs]

Answer:
On October 07, 2014, routine production ended for the TRMM PR precipitation estimates. Since PR is no longer available, the TMI/PR combined instrument (TCI) estimates are also no longer available. As products 3B42/3B43 use the TCI estimates as the satellite calibrator, September 2014 is the last month these products were produced in this way. In an effort to continue 3B42/3B43 available and usable, the real time TMPA (TMPA-RT) climatological calibrations/adjustments have been adapted for use in the 3B42/3B43. October 2014 is the first month of the climatologically calibrated/adjusted 3B42/3B43. Users should note there will be a discontinuity in the record as a result. Each individual user must determine the most appropriate use of the climatologically calibrated/adjusted 3B42/3B43 products.

The two-month latency for 3B42/3B43 remains the same with this new calibration. The delayed release for October 2014 reflects both development work and a problem with the input IR data. The previously released "provisional" data set is now considered obsolete and should not be used (although in many areas it is identical to this official release). As well, a (different) problem with the input IR for November 2014 is not yet resolved, so that data set is still in provisional status. We expect to have updated November 2014 IR data in the very near future, and thereafter run on the usual schedule.
