Spherical projection system
Science On a Sphere (SOS) is a spherical projection system created by the United States National Oceanic and Atmospheric Administration (NOAA). It displays high-resolution video on a suspended globe with the aim of better representing global phenomena.[1] Animated images of atmospheric storms, climate change, and ocean temperature can be displayed on the sphere to display environmental processes. SOS systems are most frequently installed in science museums, universities, zoos, and research institutions.
