Multiple Versus Single Scattering of Terrestrial Infrared Longwave Radiation in an Aerosol-Laden Planetary Boundary Layer

Abstract

This thesis examines the quantitative difference between multiply and singly scattered infrared terrestrial radiation in an aerosol-laden planetary boundary layer (PBL). The total net (scattering plus emission) flux densities are calculated at 11 levels. The model PBL is a summertime mid-latitude urban structure from LOWTRAN 7. The study prototype incorporates an inversion located at 2.00 km above a surface whose elevation is at sea level with a visual range of 4.0 km. The visual range and extinction coefficients decrease with height to minimums located just below the inversion to simulate a differentially mixed aerosol-laden PBL. Keywords: Physics fluid mechanics, Elementary particle physics, Nuclear scattering, Radio frequency propagation, Visibility, Smog, Lowtran.
