The Total and Spectral Solar Irradiance Sensor (TSIS)-1 mission onboard the International Space Station (ISS) collects data on the sun’s energy output. These data increase our understanding of how much energy input the sun provides to the Earth geophysical system, and also how the atmosphere responds to changes in solar output. Such knowledge is critical to improving global climate change models.
- NASA's TSIS-1 Keeps an Eye on Sun's Power Over Ozone: The Total and Spectral solar Irradiance Sensor (TSIS-1) will measure the total amount of sunlight that reaches the top of Earth's atmosphere and how that light is distributed between different wavelengths, including ultraviolet wavelengths that we cannot sense with our eyes, but are felt by our skin and harmful to our DNA.( https://www.nasa.gov/feature/goddard/2017/nasa-tsis-1-keeps-an-eye-on-su...)
