Abstract

Atmospheric transmission measurements have been made along a horizontal path through the marine atmospheric boundary layer have been made. Measurements were made in the thermal infrared region at an average spectral resolution of 0.018 micrometer in the 3 - 5 micrometer region and 0.06 micrometer in the 8 - 14 micrometer region. The Vindeby, Denmark site provided conditions of moderate wind speeds and moderate to high humidities. Both land and sea fetch conditions were encountered. Measured transmission is compared to LOWTRAN 7 predictions. Midlatitude Winter atmospheric profiles were used in conjunction with the rural aerosol model for the land fetch conditions and the Navy Maritime aerosol model for the sea fetch conditions. It was found that neither model gave the same spectral content as the measured data although the magnitude of broad band transmission was similar. It is apparent that further transmission measurements must be made in conjunction with gas, aerosol, and other environmental parameters for adequate LOWTRAN 7 model validation in the marine atmospheric boundary layer.
