Abstract:

Analyzed are various techniques for determining the number densities of atmospheric constituents. The experimental data that these techniques employ are absorption profiles of EUV solar radiation. One method analyzed is that of computing the densities by solving the linear extinction coefficient equations. Methods that assume diffusive equilibrium and a knowledge of the temperature profile are also analyzed. A method of determining an optimal payload of wavelength detectors to be used for computing the densities in a manner which minimizes the effect of the statistical uncertainty in the absorption profiles is presented.
