Following arrival at Japan’s Kitakyushu Airport at 10:30 p.m. EST Saturday, Nov. 23, the GPM Core Observatory spacecraft in its shipping container was off-loaded from the C-5 aircraft and moved to a barge to be transported to Tanegashima Island. The barge departed Kitakyushu around 6:30 a.m. EST Sunday, Nov. 24, but a third of the way to the island, an unplanned stop had to be made at a port called Saiki to protect the ship from weather and rough seas. The barge arrived at Shimama...

NASA's Dual-frequency, Dual-polarization, Doppler Radar (D3R) was transferred from GSFC to Wallops this week. D3R's dual frequencies match those of the GPM DPR radar. Some work to the D3R computing infrastructure will be performed at Wallops, and then the radar will be collocated with NASA's NPOL radar in Newark, MD.

GPM has successfully completed post-environmental Comprehensive Performance and Functional testing. These tests are performed to verify that the GPM Core satellite still meets all of its requirements after completing a suite of environmental tests (thermal/vacuum, electromagnetic interference/electromagnetic compatibility, vibration/acoustic/shock). The satellite is now being prepared for shipment to the HII-A launch site in Tanegashima, Japan.

The Sixth International Ground Validation Workshop will be held November 5 -7 in Rome, Italy, at the headquarters of the National Research Council of Italy (CNR), Institute of Atmospheric Sciences and Climate (ISAC). The workshop is organized in coordination with NASA’s Precipitation Measurement Missions Science Program.

The GPM Core satellite successfully completed vibration testing in July 2013, at NASA's Goddard Space Flight Center, Greenbelt, Md. The tests ensure that the spacecraft can withstand the vibrations caused by the Japan Aerospace Exploration Agency (JAXA) H-IIA rocket during satellite’s launch early in 2014. Sitting on a specialized mobile platform, the GPM spacecraft was abruptly moved back and forth in each of its three spatial orientations.

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...
