Time Lapse Visualization of How 10 Satellites Build a Daily Global Precipitation Map

posted by Jason Kottke   Feb 24, 2020

The first 30 seconds of this time lapse video provides a great look into how the 10 satellites that make up the Global Precipitation Measurement Constellation scan the surface of the Earth to provide daily global precipitation maps.

This visualization shows the constellation in action, taking precipitation measurements underneath the satellite orbits. As time progresses and the Earth’s surface is covered with measurements, the structure of the Earth’s precipitation becomes clearer, from the constant rainfall patterns along the Equator to the storm fronts in the mid-latitudes. The dynamic nature of the precipitation is revealed as time speeds up and the satellite data swaths merge into a continuous visualization of changing rain and snowfall.
