Abstract

Aerosols are particles in the air floating the atmospheric. They can have a huge impact about climate and human health point of view. The impact on the physical environment may be of importance as they are the capable to both scattering and absorbing incident irradiance. In this work, aerosol optical depth (AOD) of 500 nm for Nakhon-pathom, Chiang-mai and Songkhla of Thailand Penang and Sarawak in Malaysia Singapore for Singapore in the case daily average aerosol optical depth. The investigation was based on the solar spectrum of sun-photometers measured at six positions: Chiang Mai meteorological station (18.77°N 98.97°E) Nakhon Pathom(13.82°N 100.04°E) Songkhla meteorological station (7.18°N 100.60°E) Penang (5.36°N 100.04°E) Sarawak (1.49°N 110.35°E) and Singapore (1.30°N 103.78°E).When comparing AOD data from these sites for 7-years.The results show tolerances in case of the root mean square error (RMSE) between the daily retrieval of aerosol optical depth from Aqua satellite and that from the AERONET ground measurement were from the ranged of 5.34% to 18.73%. As the number of aerosol optical depth monitoring station in Thailand, Malaysia and Singapore are still very limited, it is recommended that number of the stations be increased in order to obtain more spatial coverage of information on aerosol optical depth.
