A general computer model of the ionospheric behavior during a solar eclipse is briefly described. Solutions are generated for 15 ionospheric species during the solar eclipse of 12 November 1966. These solutions are for altitudes from 60 to 120 kilometers, and include both neutral and charged species. (Author).

A one-dimensional computer simulation of the composition and the dynamics of the mesosphere and lower thermosphere between 50 and 400km is presented. The model is based on a numerical solution of large sets of partial differential equations for the conservation of mass and momentum for individual gases in an atmosphere with constant temperature and turbulent diffusion coefficient profiles. Incorporated into the model are 56 different neutral and ionic atmospheric species involved in 215 chemical and photochemical reactions. Distributions of many of the constituents are presented as determined from an application of the computer code to a midlatitude winter environment. Included are tables of the photodissociation rate coefficients as functions of the column densities of molecular oxygen and ozone for several of the atmospheric gases. Finally, the complete computer code is presented along with a detailed explanation of its structure and instructions for its use. Additional keywords: finite difference equations; equations of state.

One of the Keneshea computer codes (see AD-424 173) was adapted for use on the Ballistic Research Laboratories Electronic Scientific Computer. Using this modified code, reaction rate equations were solved for the following 15 species: e, NO2( - ), O( - ), O2( - ), O3( - ), N2(+), NO(+), O(+), O2(+), N, NO, N2O, NO2, O, and O3. The calculations were made for a 4:1 mixture of N2 and O2 at 1 torr total pressure and 300K. Rate constants as given by Keneshea and Fowler (see AD-646 975) were used. The solutions are presented as number densities versus time after the start of the irradiating electron beam. A description of the modified code is presented. (Author).
