Operational

Total and Spectral Solar Irradiance Sensor (TSIS-1)

NASA's Total and Spectral Solar Irradiance Sensor, or TSIS-1, is a mission to measure the Sun's energy input to Earth. Various satellites have captured a continuous record of this solar energy input since 1978. TSIS-1 sensors advance previous measurements, enabling scientists to study the Sun’s natural influence on Earth’s ozone layer, atmospheric circulation, clouds and ecosystems. These observations are essential for a scientific understanding of the effects of solar variability on the Earth system.
