The L3GPROF algorithm provides monthly and daily mean precipitation and related retrieved parameters from the Level 2 GPROF precipitation profiling algorithm for the GPM core and constellation satellites.


Each L3GPROF product contains global 0.25o x 0.25o gridded monthly/daily unconditional means and pixel counts. Monthly product filenames start with 3A-MO or 3A-CLIM-MO, and daily product filenames start with 3A-DAY or 3A-CLIM-DAY.

(Version 05) release:

1. Product format change:
Added dimension variables such as lat, lon, layer, lat_bnds, lon_bnds, layer_bnds. Removed
cloudIce variable but added graupel and latentHeating variables.
2. Total number of precipitation pixels (npixPrecipitation):
In Version 05, pixels with pixelStatus=0 and surfacePrecipitation > 0 are counted as
precipitation pixels. In Version 07, pixels with pixelStatus=0, surfacePrecipitation > 0 and

PPS Will Commence GPM Version 7 DPR Processing on December 6, 2021

As of November 30, 2021, PPS has ceased production of GPM V06 DPR and Combined products. Starting on December 6, 2021 we will start GPM V07 processing beginning with Data date Dec 1, 2021 for GPM DPR ONLY. On December 10, 2021 we will start GPM (reprocessing) RP for V07 back to the beginning of the mission for GPM DPR ONLY. GPM GMI and Partner data will continue at the current version (V05) until February 2022 (approximately). Please note that the Combined GPM products will not be available again until February 2022. The above does not apply to GPM NRT (near real-time) processing. An

Transitioning to NRT Ku/Ka/DPR V07

At approximately 10:30 UTC 5 December 2021 until about 00:30 UTC 6 December. The GPM near realtime will be transitioning its software to product V07 radar products. The V07 radar products have a different format from V06. Users should point their browsers to https://pps.eosdis.nasa.gov and get the V07 file specification document that provides the new format for V07 radar products. The radiometer products will remain at their current V05 until at least February 2022. There are some format changes in the L1C V07 radiometer products and substantial changes in the GPROF data presentation. Again

PPS Maintenance Jul 1 - Jul 8, 2021, Early July GPM Data Production will be on Hold

PPS will be performing crucial server updates, scheduled preventive maintenance and data product verification starting on Thursday July 01, 2021 through Thursday July 08, 2021 (Thu Jul 1, 8:00 AM EST - Thu Jul 08, 2021 Time TBD). During this period PPS will finish producing GPM data products for June 2021. GPM July 2021 production data will then be placed on hold while PPS upgrades our servers and then analyzes the GPM July data after the OS update . Please see the schedule below for the specific details and times. July 1 - 5, 2021: PPS will be closing out monthly processing for June 2021 GPM

PPS's 'ftp://gpmweb2' Service has Been Replaced with 'https://gpmweb2https'

PPS's new 'https://gpmweb2https' service is now accessible to the public and we have modified our website: https://pps.gsfc.nasa.gov/ All the previous links and source material referencing ftp://gpmweb2 have been or will be completely updated to refer to the new 'https://gpmweb2https' address. This effort will allow you to view documents and other content within your browser as you did before. As an example see: https://gpmweb2https.pps.eosdis.nasa.gov/pub/GPMfilespec/filespecMeta.G… PPS will also make 'gpmweb2ftps.pps.eosdis.nasa.gov' ftps service available as an alternative. You can

PPS's 'ftp://gpmweb2' Service will be Replaced Soon

Due to recent changes to popular web browsers (i.e. Firefox, Edge, Chrome, etc.) PPS's gpmweb2 FTP content which was viewable with a web browser may no longer display. This content will be moving to an alternate 'HTTPS' service. Consequently, all the old links and source material referencing ftp://gpmweb2 will be updated to refer to 'https://gpmweb2https' once this service is activated for the PPS public website: https://pps.gsfc.nasa.gov These changes and the new 'HTTPS' service are expected to go into effect around or before the next PPS preventive maintenance downtime on Tuesday May 04

NASA information security management authorities mandated that continued use of the File Transfer Protocol (FTP)
should not be allowed, even when used to provide access to publicly-available, non-sensitive information. This decision
was made because FTP login credentials are sent in clear text. For this reason, they mandated that all FTP sites either
convert to some form of encrypted login mechanism or be shut down. PPS determined, after reviewing available
