Abstract
Lidar detection of atmospheric molecules using a Raman scattering technique being usually limited by low signals is enhanced by integration of the forward Raman scattered light over a large atmospheric volume. This integral can be measured instantaneously in the presence of a reflector at one edge of the optical path, increasing the SNR by a factor of 100 in the case of a perfect reflector and a beam path of -2 km. Natural reflectors such as clouds leading to the same effect are also discussed.
