Mission Status

March 2015

The GPM Core Observatory successfully launched from Tanegashima Space Center, Japan, on February 27th, 2014 at 1:37pm EST. It is currently in orbit, and data from the mission is available for the public to download from a variety of sources and formats which are outlined on the PMM Data Access page.

Mission Updates

The Washington, DC area is about to get hit with a record-level snow storm, with attendant disruptions to work schedules, travel, communications, and power.  If you find that the TMPA-RT or IMERG products drop out, it is safe to assume that some combination of these effects is preventing production, and we will work to restore service when that is possible.  
With the turnover of the year to 2016, the suite of 3B40RT, 3B41RT, and 3B42RT failed to process.  Despite the holiday weekend, this was traced to a very old quality control on the date/time, fixed, and retrospectively processed to give a complete time series. Thanks to Erich Stocker and David Bolvin for this effort. The affected date/times are 160101 00UTC through 160102 12UTC.

One of our scientists noticed that the 85GHz H and V channels have missing values in ascending passes just south of 20 deg S. In that region it appears consistently since 10:45UTC which is the earliest we checked. The other channels seem fine. The counts for the 85GHz channels appear to be fine as is the geolocation. However both the 1B and 1 Base files have the missing values in that area. We are checking what is causing the algorithm to list the values as ...

Presently, PPS web services are experiencing intermittent unavailability and/or slow response times.  PPS is aware of this issue and our System Programmers are working diligently to correct these issues. The current anomaly affects our arthurhou server which include the PPS Public site http://pps.gsfc.nasa.gov/ , FTP services,  STORM: https://storm.pps.eosdis.nasa.gov/ and THOR (THOR online) , etc. We hope to have all these services restored to normal as soon as possible and will...

Effective about 18 UTC July 21 the GPM MOC stopped sending data to the PPS. This was not a satellite or instrument issue.  The problem appeared to be a network connection issue at the Emergency MOC which is currently receiving data as part of a monthly test of the backup facility. Effective 21:41 UTC the data flow from the MOC to PPS resumed. Apparently there was a major network issue on that part of the network. It has now been fixed and MOC is sending...

Starting at 16:33 UTC July 6 a filled log directory led to sh commands failing on redirecting logs to be created in that directory. A typo in the cleanup routine failed to clean our all the files after the normal 4 days. As a result they have been accumulating since the beginning of the mission.  It is unexpected that the sh failed when it could not redirect anymore.   All data products that failed have been created and put in the appropriate ...

The Tropical Rainfall Measuring Mission (TRMM) spacecraft re-entered the Earth’s atmosphere on June 15, 2015, at 11:55 p.m. EDT, over the South Indian Ocean, according to the U.S. Strategic Command’s Joint Functional Component Command for Space through the Joint Space Operations Center (JSpOC). The U.S. Space Surveillance Network, operated by the Defense Department's JSpOC, had been closely monitoring TRMM’s descent since the mission was ended in April. Most of the spacecraft was expected to...
