A107:
Understanding and attributing greenhouse gas fluxes from urban systems and major hot-spots





Session ID#: 25516

Session Description:
A major issue in quantifying and attributing fluxes of greenhouse gases from urban areas
and other hot-spots (e.g., oil and gas exploration) is that of balancing bottom-up data products with atmospheric
observations. While bottom-up data are critical for managing pollutant emissions, they are largely based on
extrapolations of source supply (e.g., oil or coal), burning efficiency, laboratory studies, and scrubbing ability.
Estimates of greenhouse gas uptake by soils, plants, and surfaces are similarly based on extrapolations of
laboratory and field studies. Conversely, top-down studies involving atmospheric observations and models can
estimate mass balances without relying on bottom-up information, but require a considered approach involving
monitoring of air composition and meteorology. In the end these two approaches need to match if we are to have
confidence in emission estimates. This session invites papers that address challenges and successes in
comparing these approaches, contrasting measurement methods, or synthesizing measurements and models.
