Glossary:Quantification
Determining an emission rate, such as mass per time or volume per time. This can be done directly through measurement of the emissions, or indirectly through estimations, calculations, and modelling.[1]
A general term for characterizing emissions numerically. Can be with emission factor bottom-up inventories or based on measurement. With measurement it often refers to emission rate estimation, but atmospheric mixing ratios may also be quantified.
Methane quantification methods for determining the size of a methane emission source in customary units if emissions rate, such as mass per time (e.g. kilograms per hour), or volume per time (e.g. standard cubic meters per hour). Methane can be quantified through engineering estimations, direct measurement of a methane source (e.g. by utilizing bagging procedures) and modeling that uses ambient measurements and meteorological data to infer an emissions rate.[2]
