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 ).

By Ellen Gray , NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 6/7/12) NASA and Nature Conservancy Agreement Supports [no-glossary]Precipitation[/no-glossary] and Migratory Bird Research The NASA NPOL radar is a research grade S-band, scanning dual-polarimetric radar. It underwent a complete antenna system upgrade in 2010 and is one of two fully transportable research-grade S-band systems in the world. It is used to make accurate volumetric measurements of precipitation including rainfall rate, particle size distributions, water contents and precipitation type...
