Precipitation Processing System (PPS) servers will be down for extended maintenance from Tuesday, September 22nd through Thursday September 24th. During this time the PPS websites, the PMM Publisher API, and the GPM research data server (arthurhou) will be unavailable. The GPM near real-time server (jsimpson) and satellite data collection will not be affected. Click here to learn more.

As farmers in Nepal prepare for the benefits of monsoon season, Dalia Kirschbaum anticipates the dangers of those torrential rains—mainly, the loosening of earth on steep slopes that can lead to landslides. In this mountainous country, 60 to 80 percent of the annual precipitation falls during the monsoon (roughly June to August). That’s when roughly 90 percent of Nepal’s landslide fatalities also occur, according to a 2015 report from the United Nations Office for the Coordination of Humanitarian Affairs. “We know a high number of landslides occur around this time, so documenting them is...

PPS Down for Temporary Maintenance 6/7/16

The PPS (Precipitation Processing System) will be down today, June 07, 2016 from 8:00am -14:00pm EDT (12:00 - 18:00 UTC). for scheduled maintenance. During this time all data transfers between PPS source and its consumer systems (GDAAC/DISC) as well as Science User services (FTP and STORM access) will be unavailable. You will be informed when PPS systems become available. We apologize for any inconvenience this may cause.

Document Description

The transition from the Tropical Rainfall Measuring Mission (TRMM) data products to the Global Precipitation Measurement (GPM) mission products has begun. This document specifically addresses the multi-satellite products, the TRMM Multi-satellite Precipitation Analysis (TMPA), the real-time TMPA (TMPA-RT), and the Integrated Multi-satellitE Retrievals for GPM (IMERG).

TRMM Satellite Out of Station-keeping Fuel

Since December 1997, TRMM and the instruments it carries have provided valuable information to researchers, the applications community, and the public. On July 8, 2014, pressure readings from the fuel tank indicated that TRMM is at the end of its fuel. As a result, NASA has ceased station keeping maneuvers and TRMM has begun its drift downward from its operating altitude of 402 km. A small amount of fuel has been retained to conduct debris avoidance maneuvers to ensure the satellite remains safe during the drift down. TRMM observations will continue as the spacecraft descends to 335 km, at
