D3R Radar Arrives at Wallops

NASA's D3R radar at Wallops Flight Facility. Shown, NASA engineer Manuel Vega NASA's Dual-frequency, Dual-polarization, Doppler Radar (D3R) was transferred from Goddard Space Flight Center to Wallops Flight Facility this week. D3R's dual frequencies match those of the GPM Dual-Frequency Precipitation Radar (DPR). 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 Successfully Completes Performance and Functional Testing

An engineer stands in front of the GPM Core Observatory in the EMI testing chamber. 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.

International GPM Ground Validation Workshop

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 meeting will focus on activities related to the upcoming launch of the Global Precipitation Measurement mission's Core Observatory, including: Developing consensus plans for post-launch assessments of satellite algorithms/products using GV measurements Reviewing results

GPM Completes Vibration Tests

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.

By Ellen Gray, NASA Goddard Space Flight Center Original www.nasa.gov Feature (published 4/12/13) This video, "Our Wet Wide World", provides an overview of the Global Precipitation Measurement Mission and its goals. Video Credit: Ryan Fitzgibbons As anyone who has ever been caught in a sudden and unexpected downpour knows, gaps still exist in our knowledge about the behavior and movement of precipitation, clouds and storms. An upcoming satellite mission from NASA and the Japanese Space Agency aims to fill in those gaps both in coverage and in scientists' understanding of precipitation. The...

3rd NOAA User Workshop on GPM: Proving Ground

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.
