Abstract
The objective of this experiment is to test techniques that try to determine the optical properties of aerosols by analyzing solar irradiance and diffused sky radiance using LOWTRAN 7. Consideration will be made on how to use these obtained optical properties of atmospheric aerosols to calibrate radiometric data of the earth's surface gathered from satellite and aircraft measurements. The technique presented in this paper is an inversion technique, which means from spectrum to properties. Data are assembled by using the so-called Portable Ground-Based Atmospheric Monitoring System (PGAMS) for the acquisition of direct solar irradiance and scattered sky radiance. In order to find optical properties of atmospheric aerosol, data of direct solar irradiance and scattered sky radiance will be compared to the results of direct solar irradiance and sky radiance generated from the LOWTRAN 7 radiative transfer code. We evaluate aerosols by fixing other atmospheric components since they are relatively stable. We try to find the best fit between data gained from PGAMS and those from LOWTRAN 7 radiative transfer codes by proper application of radiative transfer code under appropriate climatological conditions and spectral resolution.
