Oct. 13, Afternoon:

Discussion:

1.What kinds of needs from other direction?1.1 characterization of uncertainties: exposure

better quality vs higher resolutionusing model

1.2 how to use the information about uncertainty: statistical tool needs to be developed to better use the uncertainty

1.3 understand the local sources (e.g. traffic) where people live, spatial resolution at local level is important

1.4 resolution requirement depends on purpose1.5 to consider both spatial and temporal resolution at the same

time, short term1.6 many sources contributed to uncertainties besides the

concentration1.7 reasonable way back track of air pollution in the past: hindcast1.8 the changing composition of atmosphere: ozone as an indication

of photo oxidants1.9 different set data for different purpose

2. Existing and emerging tools to meet the uncertainty and resolution: high vs low tech2.1 tech development help to better measure exposure at high resolution2.2 passive samplers at high resolution

All depends on the question you ask

3. Metrics, methods and limitations:3.1 hybrid system for exposure: supersite, personnel measurement, satellite, model3.2 scientific question, criteria, methods3.3 limitations: what level of uncertainty makes difference?3.4 are we measuring right pollutants?3.5 surface information: ROS measurement?3.6 satellite is important, existing capacity is losing, high resolution satellite3.7 standardzation documentation

Test hypothesis with the atmospheric composition measurements

4. Is there evidence for the relationship between oxidative stress and mortality/morbidity

Mortality vs morbidity: to pay attention to chronicle diseasesinflammatory diseases, diabeteslinking to the composition of fine particles

30 years, 20 km resolution, o3, and PM species data: are these data useful for epi study?

Need good measurements, not necessary the best

The local gradient: traffic, woods smoke, dust, different mixtures could be different

Exposure high resolution, indoor/outdoor ratio, model validationDesign the epi study to better quantify the exposureGet everybody involved at the initial stage in designing the experimentHigh concentration data in Africa and AsiaRegional study to address the differencesMulti pollutants: not simply adding up

Audience:atmospheric chemistryhealthbroader community: chronicle diseases

get into sections:areas with different knowledge, what does this mean for different communities

summarize the existing knowledge, forward looking: research opportunitiescompelling problem statement:

dynamic change at different part of world, different sources, metrics, different approach, broad problem, gap need to be identifyeconomy: the spend on pollution control and its benefits in developed and

developing countrieschanging the global landscape, urbanizationthe relax in developed word in air pollution controlthe achievement in the past, the chance we underestimate the riska cheaper approach needed

Aims for perspective + A short report

New technology development (satellite):Opportunity to leverage the existing platform, how to bring the resources into developing world

Increasing the utility

Last paragraph to address to the funding agency

1. Science: high resolution to understand the mechanism to link to the epi study2. Surface area

Complexity of the issues:health effectsexposure: supersite, micro-scale

Satellite can be done for different purpose

What is really the new steps:better, cheaper, faster?specific composition with huge toxicity, huge cost/benefitsmore source specificevolution in US, Europe, China
