NASA presents nearly 20 years of global rain

NASA has presented its near-global estimate of rain and snow covering the past 19 years. The release allows scientists to study both long term and short term trends in Earth's precipitation.

NASA's IMERG or the Integrated Multi-Satellite Retrievals for Global Precipitation Measurement (GPM) contains combined data from a constellation of satellites operating in the orbit of the Earth to measure precipitation over the majority of the planet's surface.

This measurement is particularly valuable over the majority of the surface that lacks instruments that calculate precipitation on the ground.

Version 6 IMERG shows that the algorithm can now combine the initial precipitation estimates gathered from 2000 to 2014, during the operation of the TRMM satellite with more previous precipitation estimates gathered during the GPM satellite operation.

The record is more valuable if it's longer as said by researchers and application developers. TRMM and GPM are two satellites specifically designed to give the most credible space-based calculations of precipitations.

Both satellites are joint missions between NASA and the Japan Aerospace Exploration Agency (JAXA).
