A21H:
Understanding and Attributing Greenhouse Gas Fluxes from Urban Systems and Major Hotspots: 2. Attributing Sources and Sinks for Policy and Health Applications I Posters


Session ID#: 8054

Session Description:
Improving inventories and directly supporting mitigation of greenhouse gas and pollutant fluxes at policy-relevant scales requires not only information on total fluxes, but also identification of super-emitters, as well as detail on source locations, distribution, types, and characteristics. Recent bottom-up data products contain extensive source attributes in spatial and temporal detail, but are less reliable in terms of absolute emitted amounts. Top-down, atmospheric tracer techniques offer strong absolute emission constraints and some source attribution, but are limited by the need for dense, costly monitoring. These approaches, e.g., C-14, C-13, and co-emitted chemicals, help separate fossil fuel and biogenic emissions, associate emissions with source sectors, and even locate sources. Integrating both approaches has the potential to offer emissions verification and mitigation guidance to stakeholders. This session invites papers that seek to attribute and understand emissions from urban areas and other hot-spots with an aim towards policy application in these domains.
