Abstract
The use of lidar for measuring water vapor concentration has developed into the most useful technique for studying water vapor distribution. A brief analysis has been done for results obtained over an altitude range of a few hundred meters to 5 km. The theory of Raman scattering is briefly reviewed as background to a discussion of the optical design. The contribution of water vapor to index of refraction is examined.
