The Aerosol Optical Depth (AOD) is commonly used as a proxy of air pollutant condition.
Aerosol optical depth (AOD) is a measure of the total amount of aerosol in a vertical column of the atmosphere. This data provides values for total AOD as well as individually for organic matter, black carbon, sea salt, desert dust, and sulphate aerosols. Atmospheric aerosols are small particles or liquid droplets that are suspended in the atmosphere. They can originate from various sources, including dust, volcanic eruptions which can form aerosols, wildfires and as well as human activities such as industrial processes, vehicle emissions, and power plant emissions.
