Discussions of Coordinated Emissions Research

1. Coordinated US Initiative on Emissions Research • Suggestions to Guide this Initiative • Focus on research emission inventories • Do not interfere with regulatory inventory development process • Build on existing approaches to emissions development and observation • Facilitate new directions in collaborative emissions research • Adapt emission products for research community • Encourage active feedback between development and observation groups • Encourage multiple approaches to development and evaluation • Bring an openness to new findings and encourage sharing of results • Assess resources needed for collaborative efforts • Carry out periodic synthesis activities and progress assessments Discussions of Coordinated Emissions Research Where We Want to Go Where We Are Research Progress First Workshop, 4 December 2009, NOAA DSRC, Boulder, CO

2. Coordinated US Initiative on Emissions Research Enhance access to and usefulness of emissions data Evaluate inventories using multiple top-down methods Some Proposed Goals for this Initiative Spatial extent: US or North America Parallel regional efforts Temporal extent: Most recent 20-30 years Evaluate trends Investigate impacts of emissions on AQ and climate Encourage exchange between evaluation and development communities First Workshop, 4 December 2009, NOAA DSRC, Boulder, CO

3. Coordinated US Initiative on Emissions Research • Data access and consistency • Data clearinghouse • Inventories for multiple years with consistent methodology • Inventories for different sectors • Inventories for different regions • Input data (activities, EFs, land-use) • Observations data for evaluations Straw-man Proposals for Short-term Goals Enhance access to and usefulness of emissions data • Data usefulness • Format transfer tools • File readers • Regridding and extraction tools • Analysis and statistical tools • Speciation tools • Visualization tools First Workshop, 4 December 2009, NOAA DSRC, Boulder, CO

4. Coordinated US Initiative on Emissions Research • Evaluate merged inventory of criteria pollutants and CO2 • Carry out merge for several key years • Add other GHGs to merged inventory • Temporal variations: annual, seasonal, day-of-week, diurnal Evaluate inventories using multiple top-down methods Straw-man Proposals for Short-term Goals • Evaluate speciation of US sources • VOCs and PM • Urban, industrial, agriculture, BB • Variability between individuals in each source type • Temporal variability of source types Encourage exchange between evaluation and development communities • Evaluate consistency in emissions of aerosol and ozone precursors • Differences for different sources First Workshop, 4 December 2009, NOAA DSRC, Boulder, CO

5. Coordinated US Initiative on Emissions Research • Impacts of emission changes • Emission changes: economic activity, control strategies, land-use • Quantify impacts on AQ & climate prediction • Do observations confirm predicted AQ & climate changes? Straw-man Proposals for Short-term Goals Investigate impacts of emissions on AQ and climate • Impacts of emission uncertainties • Evaluate uncertainties in emission inventories at different scales • Quantify impacts on AQ & climate prediction • Impacts of spatial variability of emissions • Source and speciation variations for different regions • Observe and quantify impacts on AQ & climate First Workshop, 4 December 2009, NOAA DSRC, Boulder, CO

6. Coordinated US Initiative on Emissions Research • What are short-term (6 months, 1 year, 2 years, 3 years) goals with well-defined limits that could be achieved by this collaboration? • What inventory products are needed/desired that are not available now, and what are the key characteristics needed to improve research and assessment activities? Dimensions of these questions include: • Focus on emissions only or also drivers? • Timescales? • Sectoral coverage? • Update frequency? • Is this a repository, an analysis effort, and/or a data production effort? • Target resolution? • Species: multi-pollutant approaches, air quality, greenhouse gases, toxics? • What evaluation approaches show the most promise? How can we make better use of observational resources? What observations are most needed? • What is the next step? • White paper? • Proposal? • Are funding agencies willing to support this activity? • What can we do within our own agencies to promote this activity? • Follow-up meeting focusing on specific issues? Questions to Guide Discussions (from the Agenda) First Workshop, 4 December 2009, NOAA DSRC, Boulder, CO
