As part of an ongoing effort to develop a solar spectral UV irradiance model in the 200 - 400nm wavelength range using SKYLAB spectra, we are determining the quiet sun center-to-limb variation (CLV) at high resolution (~ 0.010 nm at 300 nm). Solar UV spectral radiance has been determined for the quiet sun at a variety of center-to-limb positions observed by the SO82B UV spectrograph on SKYLAB. The SKYLAB film data has been digitized using a high quality flatbed scanner. The irradiance model requires detailed knowledge of the center-to-limb variation (CLV) at full resolution over the 200 - 400nm wavelength range. In this presentation we will present the details of the analysis methods and results so far for the quiet sun. This effort is part of a NASA-LWS sponsored research program.
