On 16 June 2019 at 22 UTC several hours of missing IR data and subsequent handling of this outage caused IMERG early and late products to be produced without IR data since that date/time. To ensure consistent early and late IMERG products it was decided to retroprocess these IMERG early and late products.
All early and late IMERG products from 16 June 2019 at 22:00 UTC through June 19 were retroprocessed. You may wish to download the revised products from 16 June 2019 22:00 UTC ...
Effective around 12:00 UTC 10 June the MHS and ATMS input to real-time IMERG suddenly became unavailable due to an unexpected change in NOAA protocols. While PPS scrambles to remedy the issue, the data content of the Early and Late Runs may be reduced for the next several days, meaning lower Quality Index due to longer morphing of microwave estimates and greater contributions by IR.
All IMERG V06A Final products will be retracted later today.
On Wednesday, June 5, PPS will start the V06B reprocessing beginning with the GPM era, June 2014 - current available data. Once the GPM era is completed, PPS will start the TRMM-era, June 2000 - May 2014.
Due to capacity loads at PPS, there are no firm estimates as to how long this will take.
V06A is being retracted due to a corrupt surface coverage file in the Kalman statistics computation.
On 1 May 2019, at approximately 14 UTC, PPS will stop production of IMERG V05 in order to setup and install the new IMERG V06 code for production of early and late products.
This will require an extended period when no IMERG products will be produced or available for users. We estimate an extended period of IMERG unavailability that may last for 5 hours or more.
Upon resumption of IMERG production, V06 will start with data from 1 May
2019 hour 00 UTC. We will reestablish latency of early...
