Data Access

It was announced on Monday, June 30, that NASA requested and it was agreed to postpone the removal of SSMIS data and to continue processing and distributing DMSP data through July 31.

Department of Defense (DOD) FNMOC has announced its intention to shut down the current flow of operational SSMIS data on 30 June 2025. This is much earlier than the earlier announced date of September 2026, and would suspend the use of F16, F17, and F18 SSMIS data in GPM PPS. We are vigorously pursuing alternatives for continuing access to SSMIS data, but it seems likely that there will be an interruption, and perhaps end, to the SSMIS data streams. The lack of these 3 conically scanning radiometers will impact the accuracy of all IMERG products as they will have data from 3 fewer radiometers

All PPS services have been restarted, tested and verified including GPM Production, STORM , Registration and the PPS website. If you encounter any unusual behavior or data anomalies, please report this to the PPS Helpdesk: helpdesk@mail.pps.eosdis.nasa.gov Thank you for your patience during this unexpected downtime.

On Friday January 31, 2025, PPS detected hardware issues with PPS's Production data archive "arthurhou". Because of reported file length discrepancies, PPS is suspending access to the the 'arthurhou' production data server until they can analyze and fully resolve these issues as soon as possible. All data archiving to 'arthurhou' will be turned off during this unscheduled maintenance period. GPM production data and PPS access systems such as STORM will NOT be available for processing during that time. Please be aware that GPM NRT data file access on 'jsimpson' remains unaffected during this

The PPS has completed retroprocessing IMERG V07 products for Jan. 1, 1998 to May 31, 2000. Both the Early and Late standard HDF product and the GIS products are available on the "jsimpson" GPM near real-time file servers. Please visit our data directory for a full list of product downloads and documentation. With this retroprocessing now complete, IMERG V07 products are now available from January 1998 through the present.

ANNOUNCING a NEW IMERG Web Visualization Tool: RAIN-Global (Regional Animations of IMERG in Near-realtime - Global Edition): https://storm.pps.eosdis.nasa.gov/storm/outreach/RAIN-Global.html RAIN-Global is the next-generation, 3D global, fully interactive upgrade to RAIN, a web interface that displays recent 7-day animations of precipitation rates and accumulations from IMERG-Late data, as well as cloudiness from geosynchronous IR data. Animations are updated daily for the 7-day period ending on the prior day and are available for the past 30 days. New features include: Use your mouse or

On 18 October 2024 PPS received a corrupted IR file for 15:00 UTC, which caused all subsequent IR processing to fail and not contribute to the Early Run from 16:00 UTC on 18 October until 05:00 UTC on 20 October, and to the Late Run from 16:00 UTC on 18 October until 20:00 UTC on October 19. Subsequently, PPS manually skipped past the defective IR data file and ran all the IR data that were missed, and then reran both Early and Late for the periods listed above. These rerun products have replaced the earlier products on the fileserver. Please note the out-of-order file times to confirm which
