Abstract
A system and method for quantifying an emission source is provided. The system and method obtain a plurality of emission concentration measurements at one or more sampling points and wind data over the time the emission concentrations are measured. For each sampling point, a virtual sampling arc can be constructed using the emission concentration measurements taken at the sampling point, the wind data for when the emission concentration measurement were taken and an approximate distance to the emission source. The virtual sampling arcs can then be used to construct one or more virtual sampling grids and the amount of emissions emanating from the emissions source approximated from the virtual sampling grids.

A system for quantifying an emission source comprising:
- a plurality of sampling points operative to obtain emission concentration measurements;
- at least one emission monitor operative to take emission concentration measurements at the plurality of sampling points;
- a data processing device operatively connected to the at least one emission monitor to obtain emission concentration measurements from the at least one monitor, the data processing device operative to:
- obtain a plurality of emission concentrations measurements from the at least one emission monitor;
- obtain wind speed measurements and wind direction measurements when the plurality of emission concentration measurements were taken;
