The once-per-day imagery creates a slideshow and you can actively see how persistent and brutal the weather has been, according to Dennis Chesters of the NASA/NOAA GOES Project, who created the animation.
To create the animation, NASA uses cloud data from the GOES-East satellite and overlays it on color images of the land and ocean created by an instrument connected to NASA’s Aqua and Terra satellites.
When all of the data from the satellites is combined, it shows the winter storms moving across the Midwest and into the East Coast. Once the storms pass, the snow on the ground becomes visible.
The GOES satellite is geostationary, which means the satellite will continuously hover over the same position during its orbit around the rotating earth. This “stationary” satellite makes it easy to keep constant watch over the United States for severe weather such as tornadoes, floods, hurricanes, and winter storms.
