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...

On April 16, 2025, hardware updates on the GPM NRT and SDPS processing and network environment will impact processing and access to the systems and data products. The downtime is estimated at 20 minutes, barring any anomalies. The work is planned during a pre-existing gap in satellite data collection: 2025-04-16 gap --- 15:28:39 to 15:43:39 UTC --- 0:15:00 duration Backup times are: 2025-04-16 gap --- 17:06:04 to 17:25:27 UTC --- 0:19:23 duration 2025-04-16 gap --- 17:50:27 to 18:14:55 UTC --- 0:24:28 duration We appreciate your understanding of this interruption of GPM data.

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...

Thanks to the continuing support and work of Dr. Joe Turk of JPL, PPS has an updated version of the Cloudsat TRMM and GPM coincident datasets. These are now available for retrieval from PPS. Documentation for this V05 dataset is available on the PPS website at the following location: https://arthurhou.pps.eosdis.nasa.gov/Documents/CSAT_TRMM_GPM_COIN_ATBD… The dataset was created using the TRMM and GPM V07 products and the current Cloudsat products. The output file format is netcdf4.
