- Nóta TC relies on the controlled release of a known rate of a tracer gas, for example C2H2 or N2O. The concentration of the tracer is measured downwind, usually with a mobile monitor, with simultaneous measurement of the source gas concentration. From the known release rate of the tracer gas (kg/h) and the measured mass concentration (mg/m3 ) in the emission plume of both the tracer gas and the source gas, the emission rate of the source gas can be retrieved. The technique assumes the tracer is subject to the same dispersion and transport in the atmosphere as the source gas emissions. The tracer technique is typically used to quantify emissions from known or suspected sources (source areas), on a source-by-source basis.
