Starting at 08:38 UTC PPS stopped getting data from the GPM Mission Operations Center. Data was resumed at 17:21 UTC. However, new GPS data was sent before older GPS data. The science data was sent out of order with the GPS data. This meant that about 125 mins of 1B and 1C GMI data had no geolocation and perhaps more after this had questionable geolocation. The same issues obviously also affected the radar and combined NRT which are just missing for the period between 8:30 UTC and 17:30 UTC. All of these issues impacted the early version of the IMERG data. The late product will also be...

NOAA has reprocessed the global IR data for 10 UTC 26 April through 14 UTC 27 April due to dropped images, and all 3B41RT and 3B42RT files for this time period have been reprocessed by PPS and are now available: 3B41RT.2015042610.7.bin.gz through 3B41RT.2015042714.7.bin.gz 3B42RT.2015042612.7.bin.gz through 3B42RT.2015042715.7.bin.gz Such partial dropouts in the IR data result in somewhat lower quality for IMERG Early and Late Runs, but are not cause for reprocessing.

On Sunday, April 26, 2015, between the hours of 12 noon (17 UTC) and 12 midnight EDT (05 UTC April 27) , changes will be implemented to NASA’s Internet access. The purpose of this outage is to complete the Corporate Route Symmetry Project which is being implemented by the Communications Services Office (CSO). As a result of these changes, users can expect an outage to the below services during this time period. Services Affected: On Sunday, April 26, 2015, changes to NASA’s Internet Access will have the following impacts: Internet access to/from all NASA networks External Virtual Private...

The issues with NOAA's 4-km Merged IR data are closed and the IMERG Early and Late Runs have been restarted from the point at which they stopped. This will provide a continuous record for each, but it also means that it will take a while to process the backlog of data and catch up to the nominal latency.

Due to an outage of the input 4-km IR data, the IMERG early and late runs began failing to execute on the April 14. Because of the loss of NOAA hourly IR data, PPS has had to shut off the production of NRT early and late IMERG production. We have received no valid IR data since April 14 17:00 UTC and no IR data at all since April 15 09:00 UTC. The software is able to deal with bad data by skipping it but it is currently not configured to handle the situation of not receiving any data at all. We have received information that there are product problems at NOAA but have not received any...
