Infrared Propagation Modeling beneath Marine Stratus Clouds

Airborne measurements of aerosol size distributions are used to determine the vertical profiles of infrared (IR) extinction and absorption coefficients and asymmetry factors in eight different maritime stratus cloud regimes during unstable boundary layer conditions where the sea temperature was greater than the ambient air temperature. The average values of these parameters are determined relative to the level where the air temperature change with elevation was near a moist adiabatic lapse rate.
