Using the PPS FTP

Use of the PPS FTP to download GPM and TRMM data is free, but you are required to first register your email address. This allows the PPS to track usage statistics and send useful messages about the satellite and data availability. Once you have registered and verified your email address, return to this page to continue to the FTP to download data. 

PPS Web Services Restored

PPS web services are now functioning normally.  PPS has identified and fixed the previous production web server problem which caused the  intermittent unavailability and/or slow response times experienced for the last few days.

If you experience any further problems or inconsistencies with PPS web services including: 

PPS Network Instability

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 keep you informed as the situation changes.

PPS Data Outage

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 data again.

Initial IMERG Products Released

PPS is re-releasing the first public version IMERG products The Integrated Multi-satellitE Retrievals for GPM (IMERG) merges precipitation estimates from passive microwave sensors, geo-IR, and monthly surface precipitation gauge analysis data (where available) to provide half-hourly and monthly precipitation estimates and related fields on a 0.1° lat./long. grid over the domain 60°N-S.

GMI Production Halted for Deep Space Calibration

On December 8, 2014 and December 10, 2014 the GPM MOC will conduct deep space calibrations maneuvers that will assist in physically verifying GMI calibration changes and also help in further characterization of the GMI instrument itself.

Special processing is required for the data collected during the DSC. Therefore, PPS production of Standard GMI products will be halted on Dec 8 at 20:30 UTC. Processing will resume during normal business hours on Dec 9.
