Short summary
In this paper, we describe the use of mobile vehicle-mounted instrumentation to measure pollutants both at the surface and overhead (via a telescope) that are coming from a source. This allows us to calculate the total emissions from the source, in this case the city of Sarnia, ON, including both industrial emissions and emissions from the city populace. In this paper, we talk about improvements to the technique in the form of extra instrumentation in the vehicle.
