Atmospheric Transmission Measurements Using IR Lasers, Fourier Transform Spectroscopy, and Gas-Filter Correlation Techniques.

摘要

An extensive measurement system for atmospheric transmission field experiments is described with emphasis on the recent additions of a high resolution, scanning, Fourier interferometer system and a gas filter correlation spectrometer. Results obtained from three concurrent experiments used to generate a data base appropriate to high resolution transmission model validation are displayed. Laser extinction data, high resolution, long path atmospheric transmission spectra, and path integrated water vapor measurements are reported and discussed. Plans for future field experiments utilizing these three measurement techniques plus broadband infrared transmissometer and infrared target signature measurement are discussed.
