SUSIM UARS measurements of solar UV irradiance
Abstract
Solar ultraviolet spectral irradiances for wavelengths 115-410 nm were measured by the Solar Ultraviolet Spectral Irradiance Monitor during most of the decline of solar cycle 22. New algorithms implemented for the current data version (V19) are described. The wavelength-dependent variability during solar cycle 22 is estimated to be over a factor of 2 at H I Ly-α and less than 1-2% above 290 nm.
