Abstract:

Prediction of prenuclear event atmospheric composition in the 10 to 100 km region of the atmosphere is required for initial input to models of nuclear weapons effects. ANMAR the ASL Numerical Model of Atmospheric Radiation, Composition and Dynamics was used to generate an atmospheric composition model of the 65 deg N September stratosphere 10 to 50 km. Model results of concentrations for O3P, O21 Delta, O3, NO, NO2, NO3, N2O5, HNO3, N2O, HNO2, O1D, H2O, OH, H2O2, HO2, CH4, HCHO, and CO are presented as number density and mixing ratios in graphical form. Resultant volume production rates for several important reactions are also presented. The calculations performed by the model are fully time dependent and diurnal however, only the results for noontime are shown. Comparison of calculated results with some observations shows reasonable agreement. Author
