The GOES-16 Aerosol Optical Depth<\/strong><\/a> (AOD) derived product (below)<\/strong><\/em> provided a quantitative measure of the density of this dust — with AOD values generally ranging from 0.5 to 0.8. Note the westward-moving semicircular region where no AOD appears every day: these are areas where the product is not created, due to contamination by sun glint off the water.<\/p>\n
