Anomalies in TMPA-RT Dec. 18 - 19, 2016

Anomalies in the DMSP F-16 input data for the TMPA-RT created streaks of precipitation over open-ocean regions. We have now deleted faulty data and rerun the TMPA-RT for the period:

18 December 2016 at 09 UTC to 19 December 2016 at 18 UTC.

Please re-pull the affected data files.

There appears to be no corresponding issue with the IMERG data files due to different quality control routines.
 

Jan. 2016 GPM IMERG and Jan.-Jun. 2016 TMPA 3B42/3B43 Data Products are Being Recalled and Replaced

UPDATE 9/27/16:

January 2016 IMERG has been regenerated and posted.  This was necessary
due to an error that omitted the gauge analysis in the Final products.
Also, 3B42/3B43 have been recomputed and posted. Let me know if you have
any further questions.

PPS has removed the January 2016 GPM IMERG and January through June 2016 3B42/3B43 TMPA products from our ftp archive:

Potential Upcoming Data Outages Due to Severe Winter Storm

The Washington, DC area is about to get hit with a record-level snow storm, with attendant disruptions to work schedules, travel, communications, and power.  If you find that the TMPA-RT products drop out, it is safe to assume that some combination of these effects is preventing production, and we will work to restore service when that is possible.
 

3B4x-RT Failure and Backfilling

With the turnover of the year to 2016, the suite of 3B40RT, 3B41RT, and 3B42RT failed to process.  Despite the holiday weekend, this was traced to a very old quality control on the date/time, fixed, and retrospectively processed to give a complete time series. Thanks to Erich Stocker and David Bolvin for this effort.

The affected date/times are 160101 00UTC through 160102 12UTC.

The Transition in Multi-Satellite Products from TRMM to GPM (TMPA to IMERG)

Published Date: 
11/01/2019

The transition from the Tropical Rainfall Measuring Mission (TRMM) data products to the Global Precipitation Measurement (GPM) mission products is well underway. This document specifically addresses the multi-satellite products, the TRMM Multi-satellite Precipitation Analysis (TMPA), the real-time TMPA (TMPA-RT), and the Integrated Multi-satellitE Retrievals for GPM (IMERG).
