Abstract
The total aerosol optical depth, u, is the sum of three components: the stratospheric, μₛ, the upper tropospheric, μₜ, and the marine boundary layer, μₘ. The extinction coefficient at the sea surface, αₒ, can be m calculated from αₒ = f(μ - μₛ - μₜ)/h where h is the height of the boundary layer and f is a factor that accounts for the height dependence of aerosol extinction in the boundary layer. A boundary layer aerosol model is presented that explains the height dependence of a. Both f and h depend on the general synoptic weather pattern. This is demonstrated using a set of aircraft aerosol profiles measured over the North Pacific Ocean in the vicinity of Monterey, California.
