Change in letter on GMI NRT GPROF data products

Effective on the date and time above, all the NRY GPROF data product verson numbers were changed by increasing the letter of the data product version. This letter change means that data products were changed but no backward processing is undertaken. Only the products forward of the date/time have been altered. So, for GMI GPROF the vesion changed from V05A to V05B. Other instrument GPROF retrievals had a similar change but appropriate to their starting data product version. The algorithm itself did not change but some of the database profiles did. The algorithm team provided the following

PPS Announcing Data Product Version Change for GPM Level 2 and Level 3 GPROF Data -Available Starting Mon Feb. 04, 2019

Earlier TRMM-era processing, 1998-01 to 2000-05, will proceed when all required input data have been provided. We have attached the latest IMERG documentation for your convenience. Developers and

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.] All V06A Monthly and Half-hourly IMERG products are being retracted, as shown in this table (Encompassing all IMERG V06A data that had been reprocessed and archived -to date): ----------+----
