In this study, we propose a new cost effective approach to retrieve aerosol optical thickness (AOT) data in the visible spectrum by using sky transmittance measurements measured by a handheld spectroradiometer. The transmittance values were measured in spectral region from 350 nm to 1050 nm at the earth's surface. The well known Beer-Lambert law was used in this study to retrieve AOT values from the...
Aerosol optical thickness, AOT is one of the factors on determining air quality. The concentration of atmospheric aerosol is determined from radiances of image taken. On this study, we use AVHRR image which is appropriate to retrieve AOT from a wide coverage area. The methods of retrieving aerosol from visible and near-infrared radiance data were applied. The algorithm for mapping was based on dark...
