Browsing: TSIS-1

TSIS-1 (Total and Spectral Solar Irradiance Sensor-1) is a NASA mission designed to measure the total and spectral solar irradiance, which is the amount of solar energy received by Earth across different wavelengths. Launched in December 2017 and mounted on the International Space Station (ISS), TSIS-1 continues the long-term monitoring of solar radiation that began in the late 1970s. The mission’s instruments include the Total Irradiance Monitor (TIM) and the Spectral Irradiance Monitor (SIM), which provide critical data for understanding Earth’s climate, validating climate models, and assessing solar energy’s role in climate change. TSIS-1’s data helps scientists track changes in solar output and its impacts on the Earth’s atmosphere and climate systems.
