The algorithm for the Integrated Multi-satellitE Retrievals for GPM (IMERG) Early and Late Runs has now been upgraded to Version 04. The transition to V04 is planned to happen on Monday, March 13 by 15 UTC at PPS and the new data should start flowing down to the GES DISC as well. Access and data fields continue to be the same as for Version 03, except the version number is 04A. Initially, the data records begin on 5 February 2017 for the Late Run, and about 5 hours before the time when PPS begins processing after the switchover for the Early Run. Version 04 supersedes all prior IMERG versions...

The Goddard Earth Sciences Data and Information Services Center (GES DISC) will soon be completing its transition from FTP access to HTTPS access using NASA Earthdata Login. This transition will require GES DISC users to register with NASA Earthdata Login if they haven't already done so. To learn more about NASA Earthdata Login and registering for an account, please see https://wiki.earthdata.nasa.gov/display/EL/How+To+Register+With+Earthda… GES DISC will begin this transition starting Feb 13 2017, and expects to complete the transition mid-March. Users who currently access GES DISC...
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.
PPS received replacement PRL1KA/KU files from JAXA. PPS will reprocess the affected data including combined and downstream products (2AKa, 2AKu, 2ADPR, 2BCMB, 2HCSH, 2HSLH, 3GCSH, 3GSLH) from 2016-12-17 16:31:39 -> 2016-12-17 18:04:13. If you have obtained any of these products from our archive or through a Standing Order, etc., please discard these and use the replacement products. -------------------------------------------------------------------------- The following files and corresponding browse products will be replaced 2A.GPM.Ka.V6-20160118.20161217-S163139-E180413.015932.V04A.HDF5 2A...
We have discovered that the gauge analysis was erroneously omitted from the "production" 3B42/43 products starting with January 2016 due to issues with handling a change of data format. Thus, the production 3B42/43 are being re-computed. This does not affect the TMPA-RT suite of products, since no month-to-month gauge data are used. Note this issue also affects the current Version 3 IMERG Final Run products for January 2016. They are being recomputed as well. The current Version 3 IMERG Early and Late Runs are not affected. An update will be provided here when the corrected products are ready.
