Dr. George Huffman NASA scientists talk about the new global portrait of rain and snow and why this world-wide view of precipitation is important for everything from knowing how much freshwater is available to drink, to forecasting natural disasters like hurricanes and floods, to understanding Earth in a changing climate. NASA’s Global Precipitation Measurement mission – GPM – sees through clouds to produce the most detailed world-wide view of rain, light rain and snow every 30 minutes. Scientists can now see weather fronts in the Southern Ocean, snow at the tops of hurricanes and watch a storm on the East Coast travel across the Atlantic bringing deluge of rain that causes flooding in England. A constellation of a dozen satellites provides this unprecidented look inside rain clouds, hurricanes and blizzards, giving scientists new insights into how these storms develop and intensify, which will improve weather forecasting.For "A week in the life of rain" click here.

A video highlighting several precipitation events that occurred between August 4 and August 11, 2014, using the IMERG dataset.For complete transcript, click here. Rain, snow, hail, ice, and every slushy mix in between make up the precipitation that touches everyone on our planet. But not all places rain equally. Precipitation falls differently in different parts of the world, as you see in NASA's new video that captures every shower, every snow storm and every hurricane from August 4 to August 14, 2014. The GPM Core Observatory, co-led by NASA and the Japan Aerospace Exploration Agency (JAXA), was launched on Feb 27, 2014, and provides advanced instruments that can see rain and falling snow all the way through the atmosphere. This Core Observatory serves as the reference standard to unite preciptiation observations from a dozen satellites, which together produce the most detailed world-wide view of everything from light rain to heavy rain and, for the first time, falling snow. Scientists merged data from 12 precipitation satellites into a single seamless map called the Integrated Multi-satellite Retrievals for Global Precipitation Measurement (GPM), or IMERG. Every 30 minutes, IMERG generates a new global map with a resolution of 10 kilometers by 10 km (6.2 miles by 6.2 mi), about the size of a small suburb. These comprehensive maps allow scientists to observe changes in precipitation patterns across 87 percent of the globe and through time. Related pages
