S'COOL is a project that aims to collect data on cloud type, height, cover and related conditions from all over the world. Observations are sent to NASA for comparison to similar information obtained from satellite. Reports from a wide range of places are helpful to assess the satellite data under different conditions.

Many people take for granted how powerful clouds are in our atmosphere. It is clouds, in part, that affect the overall temperature and energy balance of the Earth. The more we know about clouds, the more we will know about our Earth as a system. The S'COOL observations help us to validate satellite data and give us a more complete picture of clouds in the atmosphere and their interactions with other parts of the integrated global Earth system.
