Comparisons of AMSR2 Current and Improved Precipitation Algorithm

Parts of Maryland and the Mid-Atlantic experienced record-breaking rain in the past week (July 21-25), causing wide-spread flooding and tree damage. The persistent precipitation was supported by a constant supply of moist tropical air.
This area was observed twice-daily by the Advanced Microwave Scanning Radiometer 2 (AMSR2) on the Global Change Observation Mission--Water (GCOM-W) satellite. CICS-MD Scientist Patrick Meyers (supporting STAR/CoRP) compared both the rainfall estimates from the current operational AMSR2 precipitation algorithm (GPROF2010V2) and its potential replacement (GPROF2017) to radar rain rate estimates.
