Abstract

The Solar Stellar Irradiace Comparison Experiment (SOLSTICE) is a three channel grating spectrometer on the Upper Atmosphere Research Satellite (UARS). The instrument measures the solar irradiance in the ultraviolet, 120 to 420 nm, with a spectral resolution ranging from 0.1 to 0.2 nm. The prime science objective is to accurately measure the solar irradiance at wavelengths important to atmospheric photochemistry, with particular emphasis on determining the variation of the solar UV flux. In order to track changes in the instrument sensitivity, SOLSTICE has the unique capability of observing bright blue stars with the very same optics and detectors used for the solar observations. Individually, the ultraviolet flux from these stars should vary by only small fractions of a percent over time periods of thousands of years, but the average flux from the twenty calibration stars provides an even more stable reference. In this report we describe the instrument design and operation and illustrate the success of this technique during the first two years of the UARS mission.
