Laser Radar Measurement of Atmospheric Temperature Profiles.

Abstract

A laser radar was implemented as a Raman lidar by redesigning two channels into the receiver. Thus two filters permitted two different portions of the Raman rotational spectrum of the air mix of N2 and O2 to be monitored. A ratio of these two intensities is a unique function of the temperature. Measurements by laser radar reproduced temperature profiles with an average absolute difference of + or - 1.0 K at altitudes up to 2.3 km as compared with radiosonde profiles. (Author)
