Cycle 24 variability of the ultraviolet solar spectral irradiance with the SOLAR/SOLSPEC 9 years of data from the International Space Station

Résumé

Accurate measurements of solar spectral irradiance (SSI) and its temporal variation are of primary interest to better understand solar mechanisms and the links between solar variability and Earth's atmosphere and climate. We present recent Ultra Violet (UV) SSI observations performed by the SOLAR/SOLSPEC spectrometer on board the International Space Station. SOLAR/SOLSPEC observations cover the essential of the solar cycle 24, from April 5, 2008 to February 15, 2017.We provide an evolution of the solar spectral irradiance during Cycle 24 using the SOLAR/SOLSPEC data thanks to revised engineering corrections, improved calibrations, and advanced procedures to account for thermal and aging corrections of the instrument. The SOLAR/SOLSPEC observations are compared with other measurements (SORCE/SOLSTICE, SORCE/SIM, SCIAMACHY) and models (SATIRE-S, NRLSSI).
