Study on Improvement of Source Intensity Estimation Method for Air Pollutant

Abstract

The purpose of this report is the improvement of the source intensity estimation. Accuracy improvement of source intensity estimation were performed on the following 4 uncertainties. 1) Uncertainty of wind direction was decreased by expanding observation time. 2) Uncertainty of emission height was decreased by removing observation data measured near a source point. 3) Terrain influence was reproduced in modified Gaussian plume model, based on wind tunnel experiment. 4) Meandering effect was reproduced by using the variance of wind direction in the field. It was verified that accuracy was improved and order estimation can be performed by these methods.
