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...

June 16, 2015, Update: 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 burn up in the atmosphere during its uncontrolled re-entry. Learn more. ----...

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has recently added all of the half-hourly and monthly *Final* IMERG data variables to the next generation of Giovanni, Giovanni-4 (G4). Giovanni is a Web-based application developed by the GES DISC that provides a simple and intuitive way for users to visualize, analyze, and access vast amounts of Earth science remote sensing data, without having to download the data.
