EUV irradiance modeling using full-disk DEM extraction

Using medium-resolution EUV spectral irradiance measured by TIMED-SEE and SORCE-XPS, we extract full-disk coronal differential emission measure distributions. These functions can be used to model the solar irradiance at high spectral resolution throughout the EUV. We discuss the robustness of our DEM reconstruction technique to uncertainties in the observations and the atomic data, and compare the spectral irradiance produced by our DEMs with the results of several proxy models.
