Abstract:

Atmospheric transmission measurements were carried out at the Cape Canaveral Air Force Station during the spring of 1977 by means of the NRL Infrared Mobile Optical Radiation Laboratory IMORL. Reduced data resulting from this effort are presented in this report for five laser wavelength regions HeNe, Nd-YAG, DF, CO, CO2. Typical high-resolution delta omega .08cm transmission spectra included in this report were derived on the basis of Fourier transform spectroscopy. An extensive set of aerosol scattering coefficient data is reported for 15 visible wavelengths and is based on Koschmieder type measurements of the contrast of distant targets. Results of extensive monitoring of the HDO path concentration with a Gas Filter Correlation Spectrometer GFCS show an abundance ratio significantly lower than the literature value of 0.03. Results of in-situ meteorological measurements and aerosol particle size distribution samplings are also reported.
