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

Final Reminder: FTP Access on PPS's 'arthurhou' Production Server, will End On January 19, 2021

This is the final reminder that starting on Tuesday January 19, 2021, PPS will transition from FTP access to FTPS access (main method) and HTTPS access (secondary method) for data transfer from the PPS's 'arthurhou' GPM Production data server Elimination of the less secure 'ftp' protocol is mandated by NASA/ GSFC security policy. This change will require PPS data users to retrieve data using alternative methods and tools. Please note that 'arthurhou' already supports FTPS and HTTPS data transfers. Details of how to access PPS FTPS and HTTPS services can be found at the links below: Click here

Temporary delay of GPM NRT Data on December 7, 2020

The Precipitation Processing System is planning to migrate the jsimpson.pps.eosdis.nasa.gov (which includes jsimpsonftps.pps.eosdis.nasa.gov) to the CentOS 8 operating system. This update will mean that GPM near real-time (NRT) data will not be available to users during the period of the update. The action is planned for Monday, 7 December 2020. We intend starting at 14 UTC (09:00 EST). We hope the outage will be between 3-5 hours. During this period no GPM NRT will be available. Some data will not be produced at the usual time during this period and will be behind normal latency. No data will

PPS Extended Maintenance and Archive Downtime Sep 22 - Sep 24, 2020 (3 Days)

The PPS (Precipitation Processing System) will be down starting Tuesday September 22, 2020 (0800 EDT|1200 UTC) -through- Thursday September 24, 2020 (Uptime- Still TBD) for a very important multi-day archive upgrade. It is not anticipated that this work will have any impact on the near real-time data servers (jsimpson) or data collection from the GPM satellite and constellation. It is important to be aware that this will be an extensive PPS GPM Archive upgrade that will impact crucial PPS services. Services that may NOT be available during this time include: PPS 'arthurhou' GPM research data

PPS Will be Down for Special Maintenance on Sunday Sep. 13, 2020

The PPS (Precipitation Processing System) will be down Sunday September 13, 2020 from approximately 1:00 PM - 7:00pm EDT (17:00 - 23:00 UTC) for scheduled GPM archive maintenance. It is projected that PPS's GPM research data server (Arthurhou) will offline for 6-8 hours and all data processing, etc. will be halted until maintenance has concluded. Data will continue to be collected from the GPM Core Observatory and constellation satellites, and access to the GPM near real-time data server (Jsimpson) will not be affected. During this time all data transfers between PPS source and its consumer

Explore 20 Years of Rain and Snowfall Data from NASA’s Precipitation Missions

IMERG Grand Average Climatology 2001 - 2019
Wednesday, September 9, 2020
A new data product merges data from the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) mission, giving meteorologists and researchers access to a 20-year precipitation record. How much rain and snow fall on Earth in any given year? NASA scientists are answering this question more accurately than ever before and observing precipitation in the most remote places on Earth. And it’s all thanks to an international constellation of satellites. At any given time, instruments onboard about a dozen satellites contribute to a record of the world’s rain and snow
