Analysis of the feasibility of an experiment to measure carbon monoxide in the atmosphere( Book )

1 edition published in 1973 in English and held by 1 WorldCat member library worldwide

The feasibility of measuring atmospheric carbon monoxide from a remote platform using the correlation interferometry technique was considered. It has been determined that CO data can be obtained with an accuracy of 10 percent using this technique on the first overtone band of CO at 2.3 mu. That band has been found to be much more suitable than the stronger fundamental band at 4.6 mu. Calculations for both wavelengths are presented which illustrate the effects of atmospheric temperature profiles, inversion layers, ground temperature and emissivity, CO profile, reflectivity, and atmospheric pressure. The applicable radiative transfer theory on which these calculations are based is described together with the principles of the technique
A Three-Dimensional Dynamical-Chemical Model of the Mesosphere and Lower Thermosphere for Upper Atmospheric Research by Fred N Alyea( Book )

1 edition published in 1984 in English and held by 1 WorldCat member library worldwide

The recent appearance of new observational data from specialized satellites and rocket probes has led to increased interest in upper atmospheric processes. The work to be reported herein is of the current status of a limited three-dimensional model of the dynamical and important chemical processes which are known to take place in the mesosphere and lower thermosphere to an altitude of about 400 km above the earth's surface. The modeling approach taken was to make use of the dynamical schemes and simplified chemical treatments embodied in our three-dimensional Stratospheric Circulation Model (SCM) developed for the study of stratospheric ozone. This model has been running on the now defunct ILLIAC-4 vector computer at NASA's Ames Research Center in California. In addition to large changes required in the existing dynamics and chemistry to reform the model for thermospheric and mesospheric levels, it was also necessary to revise the code structure to accommodate the shift from the ILLIAC machine to the AFGL CDC-660 computer. Much of this work was accomplished on the NASA machines prior to the availability, through special modems and telephone connections, of the AFGL CDC-6600. Since that time the programs have been transferred to AFGL and, while not completed, tests of the model dynamics on that machine have been undertaken
