Aerosol products

The primary products are daily, weekly, and monthly global 1 degree maps of Aerosol Optical Thickness (AOT). The weekly products are based on a
composite of one week's worth of data, and the monthly mean products are based on the average of each week's data for the month. The Aerosol fields
and contour charts are produced from NOAA-16 AVHRR 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.

These products are archived at the National Climatic Data Center in both hardcopy chart and digital dataset form.
