IMERG Precipitation and MERRA Winds

Combining multiple datasets on a single visualization can often illustrate natural processes even better than a single dataset can.  This visualization shows assimilated surface winds from MERRA (the Modern Era Retrospective Reanalysis of the Atmosphere) over the IMERG global precipitation data set for October 2014.  It was created for a forthcoming Science On a Sphere program about the Global Precipitation Measurement Mission.  Notice how the changing winds shape the areas of active precipitation, particularly over the ocean where there are no land features to affect the precipitation patterns.
