CMORPH (CPC MORPHing technique): High resolution precipitation (60S-60N)

CMORPH (CPC MORPHing technique): High resolution precipitation (60S-60N)

"CMORPH (CPC MORPHing technique) produces global precipitation analyses at very high spatial and temporal resolution. This technique uses precipitation estimates that have been derived from low orbiter satellite microwave observations exclusively, and whose features are transported via spatial propagation information that is obtained entirely from geostationary satellite IR data." (source: RDA abstract on CMORPH).

Key Strengths

High temporal and spatial resolution
