Session Biomass Burning: New Findings and Analyses from Multiple Perspectives
Bob Yokelson, Sonia Kreidenweis, Jens Redemann, and Steve Howell are convening a session at this year’s Fall AGU in San Francisco on “Biomass burning: New findings and analyses from multiple perspectives”. We hope to attract presentations that cover the latest advances in understanding open and domestic biomass burning from ground, air, or space-based measurements and modeling. We invite you to attend, present, or forward this notice as appropriate.
Detailed Session Description
Biomass burning (BB) is the largest global source of primary fine carbonaceous particles; the second largest global source of total trace gases; a major source of ozone, carbon monoxide and non-methane organic compounds; and, possibly, the major source of secondary aerosol. Biomass burning (including domestic burning) is inherently too remote, widespread, complex, and variable for any single platform or perspective to adequately characterize the whole phenomenon. Contributions from in-situ or remote sensing measurements acquired from laboratory-, ground-, air-, or space-based platforms and modeling studies are all critical in the assessment of BB as is the proper coupling of these studies. Recently there have been major advances in each approach. State of the art field campaigns with a focus on BB initial emissions and plume transport/chemistry include those conducted in Mexico, Canada (e.g. ARCTAS, ARCPAC, POLARCAT, etc), California, Brazil, Arizona, and North Carolina. Two large-scale multi-investigator laboratory studies of initial BB emissions were recently completed (FLAME-3, SERDP) and post emission processing of BB emissions in smog chambers was a focus of FLAME-3 and at least two other studies. New capabilities for satellite and suborbital remote sensing of particle properties and trace gases emitted by BB have just become available or are actively being developed (e.g., IASI, new MOPITT boundary layer retrievals, fire radiative energy and burned area products, higher spatial resolution aerosol retrievals). Supported by the improved understanding of physical processes and new constraints on emission characteristics from the observations, advances are being made in modeling the photochemistry and transport of BB plumes and in inverse modeling of global BB emissions. A comprehensive session bringing together the state of the science from all the BB disciplines (i.e., laboratory studies, field campaigns, satellite observations, and chemical transport modeling) will be of great value to the atmospheric community as it allows scientists working in the various disciplines to share recent findings, and adapt or couple their efforts spurring future progress. Contributions are encouraged from all work that updates our view of how biomass burning affects the planet.
Session Quantification of Emissions: Addressing Current and Future Challenges
Accurate and evaluated emission inventories are indispensable to scientific research on air quality and climate change. We invite contributions that address the current and future challenges facing the determination of inventories for anthropogenic, biomass burning and natural emissions of pollutants. Topics of interest include discussions of inventory consistency for multiple species across spatial and temporal scales; the use of different approaches, algorithms and models for quantifying emissions; objective and independent verification of emissions data; quantification and impact assessments of inventory uncertainties; and efforts to make emissions research more relevant and useful to policy and regulatory agencies.

Session Black Carbons (BC) Role in Global to Local Air Quality and Climate Change
BC has large positive direct radiative forcing (RF) and adversely impacts health. Interest in mitigation is growing. However, uncertainties exist on BC emissions, concentrations, transport, removal, mixing state, RF and effect on clouds. Presentations are sought on BC: ambient and emission source measurements; modeling and measurements of all aspects of RF; modeling of emission, transformation, transport, deposition and impacts; micro-physics of BC effects on clouds and precipitation; application of proxies and satellite data to constrain BC budgets; studies that inform decisions on mitigation strategies that maximize co-benefits for health and climate; evaluation of metrics to quantify climate impacts of BC mitigation.
Session “NH09: Wildfires on Landscapes: Theory, Models, and Management”
Wildfires around the globe vary in their timing, frequency, intensity, extent, and effects, and are subject to varying spatial and temporal controls. This session examines theory, models, and empirical studies in wildfire research. We explore emerging theory explaining spatial and temporal controls on wildfire size and severity, wildfire patterns along ecological gradients, and scaling laws in fire regime attributes. Similarly, we explore empirical studies and models that reveal important spatial and temporal controls and their interactions, and suggest management approaches that can influence future wildfire behavior and maintain fire-resilient landscapes in a rapidly changing climate.
