Paper Abstract

A technique has been developed by which satellite upwelling radiance measurements, MODTRAN, and the NOVAM aerosol model can be used to infer lower tropospheric extinction coefficients as a function of wavelength. This technique utilizes: 1) satellite upwelling radiance measurements for determining the total aerosol optical depth for a specific geographic location and time, 2) MODTRAN to calculate the optical depth associated with tropospheric aerosol scatter, assuming that no aerosols are being entrained into the troposphere from other source,s and 3) NOVAM for modeling the optical depth of the lower troposphere as a function of air mass parameter. By adjusting the air mass NOVAM so that the calculated optical depth matches that required for the lower troposphere, the air mass parameter for the lower troposphere can be inferred from remote satellite radiance measurements. Initial results using the EOPACE, database appear promising for inferring extinction coefficients of the lower troposphere as a function of wavelength from remote satellite radiance measurements. It also shows promise for an initial technique for modeling coastal aerosols.
