The 3rd NOAA User Workshop on the Global Precipitation Measurement Mission: Proving Ground was held from April 2 - 4th at the Earth System Science Interdisciplinary Center (ESSIC), University of Maryland in College Park, MD. The 3-day workshop was focused on identifying the use of GPM data in research and operational algorithm development, characterizing NOAA GPM Proving Ground activities and participants, and identifying training needs for use of GPM data in NOAA operations.

The NASA Precipitation Measurement Missions (PMM) Science Team for the TRMM and GPM missions met on March 18-21, 2013 in Annapolis, MD. This meeting included oral, poster, and evening working group sessions covering mission/program status, algorithm development activities, international partner reports, science activities, field campaign results, and other science team business. More than 175 scientists from 11 countries participated. The TRMM satellite is now in its 16th year...
The GPM Core Observatory is continuing its environmental testing program at NASA's Goddard Space Flight Center. Following the completion of thermal vacuum testing in January 2013, the Core Observatory team started the Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) test phase. The Core Observatory has successfully completed the Radio Frequency (RF) Self-Compatibility test and is being prepared for the next step of EMI/EMC test program. The EMI/EMC test program is...

The GPM Core Observatory completed thermal vacuum testing at NASA's Goddard Space Flight Center in Greenbelt, Md. on Jan. 16, 2013. After twelve days to carefully remove the testing equipment, stow the High Gain Antenna and GPM Microwave Imager, and lift the spacecraft out of the thermal vacuum test chamber, the spacecraft was moved back to the clean room on Jan. 28.

The GPM Core spacecraft has completed hot and cold thermal balance testing in the thermal vacuum chamber at NASA's Goddard Space Flight Center. Next it will undergo hot and cold cycle thermal vacuum testing, where the temperatures are alternatively raised to 104°F (40 degrees C) and lowered to 7°F (-14 degrees C) over the course of the next few weeks.

The GPM Core Observatory has moved from the clean room to the thermal vacuum chamber at NASA's Goddard Space flight Center in Greenbelt, Md. The spacecraft, wrapped in protective blankets, made the short trip by crane across the testing facility where it was then lowered into the 40-foot test chamber.

NASA's GPM Core Observatory satellite went through its first complete comprehensive performance test (CPT), beginning on Oct. 4, 2012 at NASA's Goddard Space Flight Center in Greenbelt, Md. The testing ran twenty-four hours, seven days a week and lasted ten days as the entire spacecraft was put through its paces.

The Mission Operation Review for GPM was held on August 15th and 16th. The agenda included operation reviews of the ground systems, launch and early orbit, instruments, spacecraft decommissioning, and overall mission activities
GPM's two solar array wings completed vibration and acoustic testing at Goddard Space Flight Center, Greenbelt, Md. The solar arrays were integrated to an identical copy of the Lower Bus Structure of the satellite for this testing. These tests and deployments demonstrate the ability of the solar array to withstand the vibrations and sounds the satellite will be subject to during launch as well as test the ability of the solar arrays to unfold once in orbit.
The GPM Microwave Imager (GMI) successfully completed a walkout deployment, spin-up and functional and interface testing after being integrated onto the core spacecraft in May, 2012. These series of tests confirmed electrical and functional performance of the GMI with the GPM Core Observatory.
