The Solar Radiation and Climate (SORCE) satellite improves our understanding of the Sun by generating new inquiry regarding how and why solar variability occurs and how it affects our atmosphere and climate. This knowledge is used to estimate past and future solar behavior and climate response. The SORCE spacecraft carries four observational instruments: Total Irradiance Monitor (TIM), Solar Stellar Irradiance Comparison Experiment (SOLSTICE), Solar Irradiance Monitor (SIM), and soft X-ray Ultraviolet Photometer System (XPS).
- SORCE measures x-ray, ultraviolet, visible, near infra-red, and total solar radiation to study long-term climate change, natural variability and enhanced climate prediction, and atmospheric ozone and UV-B radiation. (https://www.nasa.gov/directorates/heo/scan/services/missions/solarsystem...)
