Tropical Cyclone Christine

Tropical cyclone Christine was in the South Indian Ocean close to the northwestern coast of Australia when the TRMM satellite passed over on December 30, 2013 at 1113 UTC. TRMM's Microwave Imager (TMI) and precipitation Radar (PR) instruments revealed that Christine had a well defined eye. TRMM PR found that the most intense rain was falling at a rate of over 70mm/hr (~2.8 inches) in intense bands well to the east of Christine's eye. TRMM's Microwave Imager (TMI) instrument provided good coverage of Christine's eye while TRMM's Precipitation Radar (PR) had a good look at Christine's

Dr. Kirschbaum discusses her role with GPM, how she became a scientist, and how remotely sensed satellite data can be used to study and evaluate natural hazards such as landslides.

This video is the first in a series called "Faces of GPM", which will interview several GPM team members to learn what it is like to be a NASA scientist or engineer.

Profile of Steve Nesbitt, a professor of Atmospheric Sciences at the University of Illinois and a mission scientist on GPM ground validation field campaigns. Nesbitt uses the data collected to improve the representation of cloud microphysical processes using radars, aircraft probes, and surface instrumentation in satellite precipitation algorithms to improve global precipitation estimates.

GPM Core Observatory Completes Comprehensive Performance Testing

The GPM spacecraft oriented for inspections after its arrival in the clean room at Tanegashima Space Center. Image Credit: NASA / Michael Starobin On Dec. 15, the Global Precipitation Measurement Core Observatory team completed the post-shipment Comprehensive Performance Test with no significant problems. The testing took seven days to run through each of the spacecraft's systems and subsystems to ensure that the satellite is ready for space. The testing took place at GPM's launch site at Tanegashima Space Center in Japan, and was the first time all systems had been turned on since GPM's
