A COMPUTER MODEL HAS BEEN DEVELOPED WHICH CAN PREDICT THE CHEMISTRY AND PHOTOCHEMISTRY OF THE ATMOSPHERE IN THE REGIONS OF THE UPPER STRATOSPHERE, MESOPHERE, AND LOWER THERMOSPHERE. The solar flux is calculated as a function of the suns position with respect to any altitude above any coordinate point in the northern hemisphere. This means that the time dependent chemistry of the twilight periods can be treated in detail. the temperature altitude profiles are matched for seasonal and latitudinal changes. the chemical reaction set can be quickly changed, and laboratory problems can be treated by turning off the solar flux routines. the numerical integration method is new, rapid, and inherently conserves mass. A stiff equation technique is used to increase the time increment during steady-state conditions. The current model can be used to predict events that can be correlated with rocket observations, or other atmospheric measurements. Modified author abstract
