The advent of high resolution, high sensitivity X ray spectroscopy from Astro-D and AXAF missions will provide a wealth of highly detailed spectral information. The successful analysis of this data will depend on the use of nonequilibrium ionization descriptions of the radiating plasma, using accurate and complete atomic physics data sets. We present here simulated UV and X ray Oxygen spectra calculated from a time dependent, nonequilibrium hydrodynamic model using extremely detailed atomic physics data bases. Emission from static plasmas and radiative shocks are considered. We discuss the sensitivity of the calculated spectra to modeling assumptions and to approximations made in generating the atomic rates.
