Painting the World with Water (New Colorbar)
An animation depicting the build-up of precipitation data on a flat map from the Global Precipitation Measurement constellation of satellites, resulting in the IMERG global precipitation data set.
This video is also available on our YouTube channel.
The ten currently-flying satellites in the Global Precipitation Measurement Constellation provide unprecedented information about the rain and snow across the entire Earth. 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 preciptation 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. Finally, the video fades into an visualization of IMERG, the newly available data set of global precipitation every thirty minutes that is derived from this satellite data.
This is a newer version of the animation and uses a modified version of the Liquid Precipitation Rate colorbar. This newer colorbar improves the display of higher rain rates.
