Abstract

Estimating the range dependence of vapor concentration with range-resolved lidar is a challenging problem because of the weak returns provided by atmospheric aerosols and the rapid decrease in signal-to-noise ratio with range. This paper summarizes an earlier approach for constructing a statistically optimal estimator for the range dependent vapor concentration using data from multiwavelength frequency-agile lidar. The estimates of path-integrated concentration from this algorithm are compared with those made using a previously derived Kalman filter on data collected by topographic backscatter from a mountain range. In addition, the range- resolved concentration estimation algorithm is generalized to the case of multiple vapor materials. The algorithms are illustrated on a combination of synthetic and field test data collected recently by SBCCOM at the Department of Energy Nevada Test Site.
