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'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.

Ground data now being collected in northeastern Iowa by the Iowa Flood Studies experiment will evaluate how well NASA's Global Precipitation Measurement (GPM) mission satellite rainfall data can be used for flood forecasting.
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.]
Joe Munchak is a scientist at Goddard Space Flight Center who specializes in remote sensing of snow. This week he is at the CARE site in Ontario as one of the operations scientists for the GCPEx ground validation.
