Abstract :
This paper presents the potentiality of using NOAA-15 AVHRR observations for obtaining aerosol optical thickness (AOT) maps over the metropolitan area of Athens (Greece). The high correlation found between the retrieved AOT values and the PM10 measurements, suggests that the application of the differential textural analysis (DTA) algorithm on AVHRR imagery whenever available and cloud free could be used to provide daily AOT maps, indicating air quality information for the greater Athens area.
