A Day in the Life of GeoXO

The year is 2036, and a new generation of geostationary weather satellites called GeoXO is orbiting Earth to keep constant watch over the Western Hemisphere. This new generation is made up of three satellites: GEO East, GEO Center, and GEO West. The constellation is measuring, monitoring, and watching events across the United States all at the same time. Using data from current satellites, we can imagine what this new generation will see.
