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...
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...
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...
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...
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...
