Measurements that fill gaps in emission inventories: gas flares, household biomass stoves, and brick kilns

The purpose of this body of work is to fill gaps in emission inventories that in turn serve as inputs to global climate models. Emissions of aerosols are a focus because they can vary by orders of magnitude even for the same fuel, making field emissions measurements necessary. Three sources were measured in field settings, including associated gas flares, household biomass stoves, and brick kilns. For each of these sources, there were few previous measurements of black carbon (BC) aerosol and poor understanding of the variability in emissions expected. Aircraft facilitated measurements of flares in the Bakken region showed that BC emission factors were 10 times lower than previously predicted and varied over two orders of magnitude. Measurements of organic carbon (OC), BC, and particulate matter (PM2.5) in heating and cooking stoves showed that there are significantly different emissions in Tibet compared to stoves in most other regions. This work suggests that current stove emission factors used in inventories are not appropriate for all regions and stoves. Measurements of brick kiln emissions focus on PM2.5, and CO2 from a range of firing technologies in South Asia and South America. An in-depth analysis of common measurement methods suggests that the carbon balance method can underestimate particle emission factors by half when carbon emissions from the ceramic firing chemistry are ignored.
