SORCE is a NASA sponsored mission created by merging the EOS Solar Stellar Irradiance Comparison Experiment (SOLSTICE) and the Total Solar Irradiance Mission (TSIM). 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. INTRO
The SORCE spacecraft was launched on January 25, 2003 on a Pegasus XL launch vehicle to provide NASA’s Earth Science Enterprise (ESE) with precise measurements of solar radiation. It launched into a 645 km, 40-degree orbit and is operated by the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado (CU) in Boulder, Colorado, USA. lauch
SORCE carries four instruments including the Spectral Irradiance Monitor (SIM), Solar Stellar Irradiance Comparison Experiment (SOLSTICE), Total Irradiance Monitor (TIM), and the XUV Photometer System (XPS). Instruments
The NASA Solar Radiation and Climate Experiment (SORCE) science mission ended on February 25, 2020 after completing more than 17 years of excellent observations of the total solar irradiance (TSI) Conclusion
