Abstract
We describe a new method for gas flux measurements using a combination of differential absorption lidar (DIAL) and wind videography. The wind speed was measured by an imaging method, which calculates the horizontal displacement of the plume with cross correlation techniques. High spatial and temporal resolution is achieved with histogram equalization and window filtering techniques. Simultaneous measurements of the distance, the direction of the plume and the integrated concentration were provided through the lidar measurements. Alternative methods to measure the wind speed at different heights have been used to validate precision and accuracy of the new method for different geometrical combinations. An example of SO2 flux measurements from a paper pulp mill is presented.
