Experiments have been designed to test concepts for the remote sounding of the atmosphere by optical methods. In the first section an experiment is designed to measure the vertical profile of water vapor. This method is based on the differential absorption of infrared energy scattered from a searchlight beam. An analysis is presented of a Doppler method for the determination of the temperature distribution in an arbitrary direction. This method is based upon the Doppler shift that occurs when monochromatic energy is scattered by air molecules under thermally induced motion. A passive experimental technique for the determination of atmospheric temperature profiles has been analyzed. This method makes use of the variation of irradiance from a portion of the 4.3 micron CO2 band as seen by a detector scanning in elevation. Author
