Welcome
- Lorenz Magaard
Kick-Off Discussion: The Value of Cross-Disciplinary Dialogue Now
- Initiate cross-disciplinary dialogue with the aim of making science presentations as relevant as possible — know the audience and their concerns
- Jim Hansen: Air pollution and climate: Workshop scope and objectives
- Michael Scheible: Environmental perspective: Practical relevance of this science to decisions being made now about air quality regulations
- Todd Johnson: Investments in developing countries: Practical relevance of this science to decisions being made now about investments in the developing world
Quantifying the Methane Trend and Climate Forcing
- Ed Dlugokencky: Measurement constraints on the global CH4 budget
- Elaine Matthews: Global methane emissions: Historical trends, controlling factors, and future prospects
- Hugo Denier van der Gon: Declining estimates of methane from rice agriculture (PPT presentation, 2.8 MB)
- Paul Gunning: Opportunities for global methane emission reduction (PPT presentation, 3.0 MB)
- Markus Amann: Emission trends of anthropogenic air pollutants in the Northern Hemisphere (PDF presentation, 0.1 MB)
- Michael Prather: "Air pollution" control over (indirect) methane emissions (PPT presentation, 1.1 MB)
Panel Discussion
- Is it possible to achieve a global warming success story with
methane, i.e., can we achieve a real world scenario with
decreasing CH4?
What information/research is needed to better address this issue? (Chair: R.G. Derwent)
Emission Inventories — A Challenge: Our Uncertain Knowledge of Emissions
- David Streets: Overview of gas and aerosol emissions (PPT presentation, 4.2 MB)
- A.P. Mitra: Indian inventory of climate forcing pollutants
- Yuanhang Zhang et al.: Aerosol pollution and its sources in major cities of China
- Zhanqing Li: Estimates fire emissions from boreal forest fires (PPT presentation, 6.9 MB)
Quantifying the Ozone Trend and Climate Forcing
- Daniel Jacob: Factors controlling tropospheric O3 and the coupling from regional to global scales (PPT presentation, 1.2 MB)
- Jos Olivier: Global emissions of ozone precursors: Sources, trends and uncertainties
- R.G. Derwent et al.: Projections for future ozone change driven by changes in climate and precursor emissions
- Fred Fehsenfeld: Ozone transport to and formation in the remote troposphere
- Loretta Mickley et al.: Climatic implications of changes in tropospheric ozone (PPT presentation, 5.9 MB)
- Hajime Akimoto: Recent changes of ozone in Far East Asia and Europe (PPT presentation: Part 1, 1.7 MB; Part 2, 3.7 MB)
Panel Discussion
- Is it feasible to halt the growth of global tropospheric
O3 or even achieve a reduction?
