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.]
