GPM IMERG V06A is being retracted for correction

An error has been discovered in processing the initial batches of V06 IMERG Final Run months.  A design choice in the code ended up retaining microwave precipitation estimates in the latitude band 60°N-S when there is snow/ice on the surface, rather than masking out the estimates due to low performance in such cases.  [Masking for microwave retrievals over surface snow and ice outside that band is correct.]

PPS Announces GPM IMERG V06 Data Availability Starting after 3/13/2019

Starting  this week (Wednesday March 13, 2019 or soon after) PPS will commence GPM IMERG data reprocessing for IMERG V06.  PPS will start reprocessing with the GPM-era data and will make these products available as they are archived.

Thereafter, we will reprocess the TRMM-era data.  The first available products for the GPM-era will start with June 2014. TRMM-era products will span June 2000 - May 2014.   Earlier TRMM-era processing, 1998-01 to 2000-05, will proceed when all required input data have been provided.

PPS Announces Level 2- Level 3 PRPS MT1 SAPHIR V06 reprocessing

PPS will be doing a full reprocessing of Level 2 - Level 3 PRPS MT1 SAPHIR data as V06A for release starting Wednesday March 06, 2019.  In addition to the regular data products there will be a Climatology product as with the current L2-L3 GPROF data products.  The following data will be reprocessed as V06A:

Top 5 GPM Research Highlights

Top 5 GPM Research Highlights

GPM celebrates its fifth anniversary since launching from Tanegashima Island, Japan on February 27, 2014. This milestone not only marks the launch but also the many scientific research accomplishments that GPM has made in advancing our understanding of precipitation, from light rain to intense thunderstorms, to further our understanding of the water cycle. 

Here are five of GPM’s most significant research accomplishments and their contributions to weather and climate science in its first five years in space:
