Quantification of Gaseous Emissions from Gas Stations, Oil Wells and Agriculture using Optical Solar Occultation Flux and Tracer Correlation Methods

摘要

Emission measurements of VOCs from small sources have been carried out with several unique optical remote sensing techniques during a 2 month campaign in the Los Angeles metropolitan area. The small sources studied correspond to areas with oil wells and cisterns, treatment plants oil storage depots, petrol stations, fuel islands and a few oil platforms. In addition ammonia emission from farming was demonstrated. In the presentation we will describe the used methods and discuss the obtained emissions. The methods were compared in several side-by-side measurements with other techniques and in an experiment with a controlled tracer source release.
