The Solar Dynamics Observatory, coupled with existing and planned space missions
are significantly contributing to our understanding of parts of the solar spectrum.
Substantial progress has also been made on the physical understanding of these
measurements and their solar origins. To refine this understanding, and to make
quantitative estimates of radiative variability that can be utilized in models
or analyses related to the terrestrial atmosphere, requires a detailed comparison
and contrast of high spectral resolution spectra with extant observations, and
a characterization of the observed variability measured at a lower spectral
resolution. This study also needs to be performed, self-consistently over much
of the solar spectrum. In this presentation, we outline our approach of combining
observed solar images with semi-empirical models and theory for calculation
of a mixed line+continuum spectrum emitted from realistic representations of
the observed solar disk. We present specific results in the UV and EUV spectrum
and related observations.
