The Solar Ultraviolet Spectral Irradiance Monitor (SUSIM) aboard the Upper Atmosphere Research Satellite (UARS) has measured the solar UV irradiance since October 1991. This 13 year time period includes a secondary maximum of solar cycle 22, the ensuing solar minimum, the maximum of solar cycle 23, and its declining phase. SUSIM maintains the calibration of its changing responsivity through a combination of measurements of four stable onboard deuterium calibration lamps and measurements of infrequently exposed reference channels. The wavelength-dependent UV irradiance time series exhibit two dominant periodicities, that of solar rotation (27~days) and solar cycle (11~years). The solar cycle variation of the UV irradiance was similar for solar cycles~22 and 23: about 55% at Ly-α , about 7% at 205~nm, and less than 1% above 300~nm. The SUSIM measurements are compared with other coincident measurements including those of SOLSTICE over a similar time period and with the Mg~II core-to-wing ratio index. Prospects and requirements for continued and possibly improved monitoring of the solar UV irradiance are discussed.
