Paper Abstract

The central parameter in the quantification of chemical vapor plumes via remote sensing is the mean concentrationpath length (CL) product, which can lead to estimates of the absolute gas quantity present. The goal of this paper is to derive Cramer-Rao lower bounds on the variance of an unbiased estimator of CL in concert with other parameters of a general non-linear radiance model. These bounds offer a guide to feasibility of CL estimation that is not dependent on any given algorithm. In addition, the derivation of the bounds yields great insight into the physical and phenomenological mechanisms that control plume quantification.
