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 deviation level.

L'invention concerne un procédé amélioré permettant de déterminer si un point de mesure, mesuré à l'aide d'un système LIDAR à absorption différentielle (DIAL), représente un point de panache ou un point de non panache. Des longueurs de cheminement de concentration (CPL) d'une pluralité de points de mesure sont déterminées. Une CPL de non panache moyenne, CPZ, est obtenue. Pour chaque point de mesure, un écart standard, CPLsd, est calculé sur la base d'une propagation d'erreur de premier ordre et il est déterminé que le point de mesure représente un point de non panache lorsque la règle de décision de Hooshmand (HDR) est satisfaite. La HDR est représentée par la formule (I) dans laquelle cpl représente la CPL correspondante du point de mesure testé et T représente un niveau-seuil d'écart standard.
