Abstract: A simple model is used to estimate the accuracy of a number of methods for treating the solar zenith angle in determining photodissociation rates for the modeling of stratospheric ozone. The method of averaging the rates ...

Abstract: Fluctuations in the atmospheric ozone column may significantly increase mean transmitted ultraviolet radiation at biologically sensitive wavelengths, and increase mean photodissociation rates in the lower stratosphere.

Abstract: A technique for following the circulation of a tracer in a turbulent fluid is developed from the integral form of the mass continuity equation. Numerical methods based on this technique are shown to be stable, to ensure ...
