Abstract:

Dr. L.C. Jacchia 1971 has developed a static diffusion model of the atmosphere that matches parameters at 150 km and the observed densities from satellite drag at greater heights. His report presents tables showing temperature, density and composition as a function of height and exospheric temperature. The Jacchia model has been used in working programs by reading the tables and converting from log densities to simple densities and vice-versa, to interpolate the tables and make the necessary corrections. This report presents a FORTRAN subroutine which gives the precise density information along with the appropriate corrections directly by using the analytic equations. Author
