Abstract
Methods for calibrating an emission rate measurement of a gas are provided. The methods involve discharging a reference gas that is the same or a different composition than a subject gas. If the same or similar, then a combined emission rate of the reference and subject gas is measured, as well as an emission rate of the subject gas only. A deviation, or an one or more adjusted parameter, of the combined and subject gas measurement from the reference gas discharge rate is used to calibrate the subject gas measurement. If the reference gas is different, the emission rates of the subject and reference gas are measured, and a deviation, or an one or more adjusted parameter, of the measured rate from the discharge rate of the reference gas is used in calibrating the subject gas measurement. The methods may also use a modified 2-D tracer measurement as a reference.
