摘要：The aerosol optical thickness (AOT) product can be used to provide an estimate of air quality over the land surface. The measurements have been acquired around Mina, Saudi Arabia during the Hajj season 1426H. A technique based on spectroradiometer measured transmittance data was applied to derive the aerosol optical thickness (AOT) in the atmosphere. We selected the spectral values at 550nm for the present analysis. The PM10 (particles measuring 10-micron or less) were measured simultaneously with the measurements of the transmittance data. An AOT map was generated using Kriging interpolation method. The well knows Beer-Lambert law was used in this study to retrieve AOT values from the measured transmittance values. The results show that the AOT values were linearly correlated with the PM10 readings using the spectroradiometer over the land surface in Mina, Saudi Arabia
