The Climate Prediction Center morphing method (CMORPH) provides precipitation estimates obtained every
thirty minutes from passive microwave satellite scans that are propagated by motion vectors derived from
geostationary satellite infrared data. In addition, the shape and intensity of the precipitation features are modified
(morphed) during the time between microwave sensor scans by performing a time-weighted linear interpolation.
This process yields spatially and temporally complete microwave-derived precipitation analyses, independent of
the infrared temperature field. CMORPH showed substantial improvements over both simple averaging of the
microwave estimates and over techniques that blend microwave and infrared information but that derive estimates
of precipitation from infrared data when passive microwave information is unavailable. CMORPH provides precipitation
at a global scale at high spatial and temporal resolution. 60N - 60S precipitation.
