Paper Abstract

This paper presents the results obtained through the application of atmospheric correction on ASTER images for deriving the aerosol optical thickness (AOT). The literature shows that there is a gap in correlating the determined or measured AOT through the visible and near-infrared spectrum with the air-pollutants such as PM10, PM2.5, CO2, etc. This research investigates such aspects by acquiring sun-photometer measurements, image data, and air-pollutants measurements during the satellite overpass of the urban areas in Paphos and Limassol District in Cyprus. AOT values delivered from MODIS satellite images are regressed against the sun-photometer ground-based measurements. The determined AOT values from both sources are compared with the AOT values retrieved from ASTER and/or LANDSAT TM /ETM+ images. Preliminary results show that the AOT retrieved after applying an atmospheric correction from the images was very near to those found from the sun-photometers acquired simultaneous during the satellite overpass.
