Abstract:
1. A system for determining emission rate of a gas from a source comprising: a selector for designating an in-plume area extending across a plume of gas, the in-plume area including a length dimension greater than a width dimension, a processor for determining an area-integrated concentration value for the in-plume area, a wind vector received by the processor, and the processor for determining the emission rate of the gas based on the area-integrated concentration value and a vector component of the wind vector, the area-integrated concentration value is based on a plurality of concentration path length (CPL) measurements obtained by an airborne platform, the selector includes a drawing tool for drawing a polygon to surround the in-plume area, and the polygon includes a rectangle or a parallelogram having the length dimension oriented along a flight path of the airborne platform.
