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.
