Aerosol Optical Thickness (100 KM) - The primary products are global one degree maps of aerosol optical thickness based on one week's worth of data. Currently they are created from AVHRR channel 1 optical thickness retrievals from AVHRR global area coverage (GAC) data. Optical thickness, or optical depth,is a dimensionless quantity that indicates the amount of depletion that a beam of radiation undergoes as it passes through a layer of the atmosphere. Optical depth is a function of the density, composition, temperature, pressure, and volume of the layer. Aerosols are defined as suspensions of liquid droplets or solid particles in the atmosphere, including dust, smoke, sand, volcanic ash, sea spray and smog.
