UARS Solar-Stellar Irradiance Comparison Experiment (SOLSTICE) Level 3BS V018 (UARSO3BS) at GES DISC

The Solar-Stellar Irradiance Comparison Experiment (SOLSTICE) Level 3BS data product consists of daily, 1 nm resolution, solar spectral irradiances and selected solar parameters. The instrument was a three-channel ultraviolet spectrometer that measured the magnitude of solar and spectral irradiances in the wavelength range from 119 to 420 nm. The design of the instrument allowed for observations of both the sun and bright blue stars, whose spectra is assumed to be constant. SOLSTICE was flown on NASA's Upper Atmosphere Research Satellite (UARS) and designed to measure the full disk solar irradiance with high precision and accuracy to follow short-term (minutes to hours), intermediate-term (days to weeks), and long-term (11 year sunspot, and 22 year solar magnetic field cycles) variations in the solar output. The SORCE Level 3BS data were processed with the version 18 algorithm.

The SOLSTICE Level 3BS data consists of 1 granule per day. The data are normalized to an earth-sun distance of 1 AU, and instrument degradation have been applied to the data. Included with the primary solar spectral irradiance values are daily average integrated intensities of Lyman alpha (121.6 nm), O-I (130.4 nm), C-IV (154.8 nm) and C-I (156.1 and 165.6 nm), and core-wing ratios of Mg-II (280.0 nm) and Ca-II (393.3 nm), as well as Carrington latitude and longitudes. The data files are available in a binary record oriented format.
