STUDIES ON SOLAR AND TERRESTRIAL RADIATION TRANSFER THROUGH THE EARTH-A1'MOSPHERE SYSTEM, INCLUDING ATMOSPHERIC GREENHOUSE EFFECT

Abstract
This work deals with very interesting problem concerning studies on solar and terrestrial radiation transfer through the Earth-atmosphere system, including atmospheric greenhouse effect. Greenhouse gases (H20, C02,
03, C, N20 and CFCs ) , aerosols, and clouds play an important role
in climate change. Most of these parameters are effective absorbers and/ or scatterers, and this may perturb the energy balance on the Earth. Consequent warming or cooling in the Earth-atmosphere system may occur, such as increase in the Earth's surface temperature due to greenhouse warming effect, cooling due to aerosol scattering, or change in meteorological conditions. The evidence that human activities are altering the concentration of these greenhouse gases and the other parameters in the atmosphere and intensifying the greenhouse effect is incontrovertible, but there is a considerable uncertainty about the consequences for climate change processes.
The modeling objective of this study is to give an improved understanding of how changing greenhouse gases concentration, aerosols and clouds affect on the variability of solar and terrestrial radiation of the Earth-atmosphere system, radiative forcing, rate of temperature change and the equilibrium warming. A research program of data analysis and radiative transfer modeling using standard and local atmospheric conditions for specific location has been carried out by applying the developed Streamer radiative transfer model given by (J. Key, Univ of Colorado U.S.A) during the time period from 1982 to 1992.
The methodology of this study is totally devoted to : description on the location of study, measuring methods of greenhouse gases, collecting data from ground and satellite measurements, applied model, computational methods involving theoretical equations and FORTRAN programs (Appendices A, B and D) are designed to calculate the following (a) : net shortwave and longwave radiative fluxes; (b) : rate of temperature change; and (c): equilibrium warming ofthe most greenhouse gases.
