ABSTRACT:
An improved method for determining whether a measurement point, measured using a differential absorption LIDAR (DIAL) system, represents a plume point or a non-plume point. Concentration path lengths (CPL's) for a plurality of measurement points are determined. An average non-plume CPL,CPL, is provided. For each measurement point, a standard deviation, CPLsd, is calculated based on first order error propagation and it is determined that the measurement point represents a non-plume point when the Hooshmand decision rule (HDR) is met. The HDR is given by,(cpl-CPL_CPLsd)2>(T)2,where cpl is the corresponding CPL of the measurement point being tested and T is a threshold standard deviation level.
