Abstract
A simple image processing technique applied to channel 1
and channel 2 of the NOAA AVHRR sensor may be used to
discern variations in aerosol particle size distribution.
Ratios of the channel 1 albedo to the channel 2 albedo are
calculated and displayed as an image. High ratio values are
shown to indicate increased levels of submicron aerosols,
while low ratio values indicate increased levels of supermicron
aerosols. Horizontal variations in aerosol distributions
may be observed directly by noting variations in ratio
values, and vertical distributions may be inferred through
the application of appropriate regional models of aerosol
transport. A model of offshore advection of urban particles
within the marine boundary layer is presented. Interpreting
ratio values in light of this model, the offshore transport
of urban aerosol particles is observed in AVHRR imagery of
southern California during the period 17-25 October 1984.
