NASA's Global Precipitation Measurement (GPM) mission launched on Feb. 27, 2014. It is a collaboration between NASA and the Japan Aerospace Exploration Agency and acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is NASA's Integrated Multi-satellitE Retrievals for GPM data product, called IMERG, which combines data from all 12 satellites into a single, seamless map. The map covers more of the globe than any previous precipitation data set, allowing scientists to see how rain and snow storms move around nearly the entire planet. As scientists work to understand all the elements of Earth's climate and weather systems, and how they could change in the future, GPM provides a major step forward in providing the scientific community comprehensive and consistent measurements of precipitation.

Horizontal Precipitation Accumulation colorbar. Low rain amounts begin in light blue. As precipitation amounts increase colors transition though cyan, green, yellow, red, dark red, violet, magenta, peach, and finally white for the highest rainfall amounts.

The accumulated precipitation product visualized here begins on January 1, 2015 and runs through July 16, 2015. This visualization shows the rainfall accumulated over the oceans as well as the land. The heavy rainfall throughout Northern Texas as well as the drought in Southern California can also be seen.
