Abstract:

A carbon dioxide laser source and a long path multipass absorption cell have been used to measure the water vapor and carbon dioxide transmittance at three wavelengths in the 8 to 12 micron atmospheric window. The carbon dioxide data were analyzed by theoretical equations to determine the line strengths and Lorentz half width. An empirical equation was derived relating the water vapor transmittance to the amount of water vapor in the path. Author
