Concentration of aerosols in the atmosphere. False-colour satellite image of the world showing the aerosol optical depth of the atmosphere from region to region. Aerosol optical depth provides a measure of the concentration of aerosols (suspensions such as dust and liquid droplets) in the atmosphere. Blue areas indicate the presence of relatively few aerosols,whereas the yellow areas,such as the band along the equator,correspond to the highest concentrations. The image was recorded by the SAGE II (Stratospheric Aerosol and Gas Experiment) satellite between August 27 and October 6 1986. Data supplied by McCormick,Kent and Schaffner,NASA/Langley | |
