There exists a growing need to improve the accuracy of measurement of the absolute solar flux within the wavelength range 120-400 nm. Although full-disk solar fluxes and variations thereof in the 120-400 nm region are required to model the solar atmosphere, current increased interest in the measurements arises from their importance in modeling the terrestrial atmosphere. The Solar Ultraviolet Spectral Irradiance Monitor (SUSIM) experiment under development for flight aboard the Space Shuttle and the Upper Atmospheric Research Satellite is described. SUSIM will monitor the solar flux in the 120-144 nm region with high precision, using an in-flight calibration system to reduce absolute error to less than 10%, and error relative to the 400 nm continuum to less than 1%.
