NASA Begins IPHEx Field Campaign

NASA Begins IPHEx Field Campaign

Rain, ice, hail, severe winds, thunderstorms, and heavy fog – the Appalachian Mountains in the southeast United States have it all. On May 1, NASA begins a campaign in western North Carolina to better understand the difficult-to-predict weather patterns of mountain regions. The field campaign serves as ground truth for measurements made by the Global Precipitation Measurement (GPM) mission's Core Observatory.

D3R Radar Arrives at Wallops

D3R Radar Arrives at Wallops
Image Caption: 
NASA's Dual-frequency, Dual-polarization, Doppler Radar (D3R) was transferred from GSFC to Wallops the week of 10/28/13.

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.

Note the low snow amounts on the ground. Sensors left to right are: ADMIRARI (radiometer; U. Bonn), D3R (radar; NASA), DPR (radar; U. Koln). [This dual-precipitation radar (DRR) is not the same as to be on the GPM spacecraft.]
