Monte Carlo computer simulations of ground-based and space-based coherent DIAL water vapor profiling

Ground-based and space-based coherent DIAL water vapor measurement performance at the 2.1-microm Ho:YAG wavelength is presented using a Monte Carlo computer simulation. The stochastic simulation allowed improved modeling of lidar system, platform, atmospheric, and data processing parameter effects on performance and better understanding of their interrelationships. Results indicate that accurate water vapor measurements in the lower troposphere are potentially achievable from both ground- and space-based platforms.
