Science On a Sphere: A Global Tour of Precipitation from NASA

Precipitation (falling rain and snow) is our fresh water reservoir in the sky and is fundamental to life on Earth. A Global Tour of Precipitation from NASA shows how rain and snowfall moves around the world from the vantage of space using measurements from the Global Precipitation Measurement Core Observatory, or GPM. This is a joint mission between NASA and the Japanese Aerospace Exploration Agency (JAXA) and offers the most detailed and worldwide view of rain and snowfall ever created. This narrated movie is created for Science On a Sphere, a platform designed by NOAA that displays movies on a spherical screen. Audiences can view the movie from any side of the sphere and can see any part of Earth. During this show viewers will be guided through a variety of precipitation patterns and display features such as the persistent band of the heaviest rainfall around the equator and tight swirls of tropical storms in the Northern Hemisphere. At subtropical latitudes in both hemispheres there are persistent dry areas and this is where most of the major deserts reside. Sea surface temperature and winds are also shown to highlight the interconnectedness of the Earth system. The movie concludes with near real-time global precipitation data from GPM, which is provided to Science On a Sphere roughly six hours after the observation.
