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 formula (I) , 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 formula (II) where cpl is the corresponding CPL of the measurement point being tested and T is a threshold standard …
