GPM

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.

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

Regions of unrealistically high values appeared in the IMERG Early and Late files starting around 00:00 UTC on 17 October 2024. Upon investigation, GPM scientists detected an operational problem on the GPM Core Observatory around 15 October 2024 that caused some corrupted CORRA data to be added to the CORRA-GMI calibration accumulator files for the IMERG Early and Late Runs. These anomalous data affected the calibration when it was next updated (on 17 October 2024). Repaired calibration files were applied at 06:00 UTC on 2 November 2024. The time spans of the unrealistic calibrations in Early
