Total Precipitable Water



This real-time animation from NOAA shown the total amount of moisture in the atmosphere, updated daily. The atmosphere contains an enormous amount of moisture that circulates around the globe. However, not all of it actually condenses into rain, sleet, or snow since the right balance of pressure and temperature are needed to create precipitation. This dataset uses data from the Advanced Microwave Sounding Unit, AMSU, which is attached to the NOAA Polar Environmental Orbiting Satellites NOAA 15, NOAA 16, and NOAA 17.
