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

Resumption of GPM Core Observatory Science Operations and NRT Data

On 26 August 2020 at approximately 14 UTC GMI was commanded into science operations mode. Since that time PPS has been producing level 1 and level 2 GMI data. Everything continues to be nominal with GMI science operations. On 26 August 2020 at approximately 23 UTC the DPR was commanded into science operations mode. Since that time PPS has been receiving 1B data from JAXA and producing L2 products including the combined GMI/DPR product. Everything continues to be nominal with DPR science operations. Users are free to resume retrieving GPM NRT data. Initial investigation indicated that the

Currently Not Receiving Data from the GPM Core Satellite

Effective about 11 UTC 19 August 2020, the GPM Mission Operations Center (MOC) stopped receiving data from the GPM Core Observatory satellite. The Flight Operations Team (FOT) is currently assessing the situation. They are working to determine what configuration needs to be accomplished to reestablish data from the satellite. This will likely take a while and there will be no GPM Core Observatory data products available until communications has been successfully reestablished and tested. The IMERG product will continue to be produced but no GMI data will be included in either the early or late

TKIO Annoucement - PPS is Announcing a New tkio-3.9 Release

PPS has created a new PPS/GPM Science Algorithm Toolkit (TKIO) package which includes all the latest production formats. Those wishing to access new production data products listed below using C and Fortran interfaces may wish to download this TKIO package. Those using development TKIO versions that include the newer products do not need this public distribution, it is optional. This 3.97 TKIO includes all production formats including the recent additions of the V06X radar products and 3B42/3 in HDF5. The direct link is ftp://gpmweb2.pps.eosdis.nasa.gov/pub/PPStoolkit/GPM/tkio-3.97/tkio-3.97
