Aerosol Optical Thickness

Daily mean Aerosol Optical Thickness (AOT) is derived for every one-degree latitude and longitude box covering the area from 52° N to 17° N and 114° E to 150° E. AOT is defined as the aerosol optical thickness at 500 nm of wavelength, and is retrieved by referring to look-up tables generated by radiative transfer calculations. In this monthly report, AOT is expressed in a three-digit integer form (multiplied by 100), e.g., 1.23 is expressed as 123. A '---' mark represents either a land area or a location where there is no valid data.
