Abstract:
The SOLar-STellar Irradiance Comparison Experiment (SOLSTICE) aboard the Solar Radiation and Climate Experiment (SORCE) spacecraft has been measuring solar spectral irradiance (SSI) since early 2003. SOLSTICE observes from 115-300 nm with a spectral resolution of 0.1 nm. In addition to the daily solar measurements over the last 17 years and parts of three solar cycles, we have also observed spectral irradiance from bright stars, the Moon, and comets. Stellar occultations at 140 and 240 nm have measured Earth’s atmospheric atomic oxygen (O) and ozone (O3). SOLSTICE has even measured the slow evolution of the energetic particles in the South Atlantic Anomaly. This talk will summarize the highlights of the SOLSTICE observations and data products obtained over the last seventeen years.
