Variability of Aerosol Optical Depth and its Relation with Natural and Man Made Hazards
Abstract
Aerosols have direct influence in global climatology and play adverse effect on human health, and the study of spatial and temporal variations of aerosol optical depth (AOD) is important. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard the Terra satellite is providing spatial and temporal information about the continental and oceanic aerosols. The present study is based on the analysis of aerosol optical depth retrieved from MODIS data from March 2000 to December 2003. Several maxima values are found to be associated with the occurrence of various natural and man made hazards such as: forest, coal mine and oil well fires, volcanic activities and large blasts. The study shows dynamics of AOD concentrations with seasonal wind patterns over the eas
