Workgroups Resources Data North American Integrated PM2.5 Data Set Title: North American Integrated PM2.5 Data Set Organization: Center for Air Pollution Impact and Trend Analysis (CAPITA) Description: This is a long term North American fine particle mass (<2.5 micrometers) data set created by integrating data from 16 historical and active fine particle monitoring networks. The data set contains data from ~500 urban and rural monitoring sites in the US and Canada from 1979 through February 1997. This data set was created to support spatial and temporal PM fine trend analysis, as well as the investigation of the causal factors for the fine particle air quality. Except for unit changes, the fine mass concentrations have not been altered from that received from the data suppliers.

The distribution of back trajectory segment endpoints over a latitude-longitude grid is examined as a function of measured concentrations at the fixed monitoring site. Grid cells in which segment endpoints are preferentially associated with high concentrations are then identified as candidate emissions sources. The method correctly identifies southern California as a source of CH3CCl3. An objective rationale is developed for screening out chance associations, attributable to statistical fluctuations, and the results are evaluated for real and hypothetical tracers with known, simple distributions.

Incorporation of related data into the spatial interpolation of fine mass aids the interpolation. This paper describes the methodology used in deriving fine particle maps for the U.S. by using visibility (280 sites) and PM10 data (~1000 sites) as fine mass surrogates. The approach utilizes existing fine mass concentration data as the measured "anchor points" for the derived maps. The higher resolution spatial coverage of the visibility and PM10 networks combined with their relationships to fine mass results in more detailed fine mass maps. Quarterly fine mass maps are derived for 1988-92.

A relation for the decrease of pollutant concentrations with increasing elevation is applied and the elevation correction is performed using a monitoring site's elevation relative to its surrounding terrain. Topographical data and meteorological scale height data are used in conjunction with PM10 concentration data to interpolate PM concentrations.

The temporal interpolation method requires the estimation of fine mass for two days sandwiched between the 3-day sampling intervals. The interpolation utilizes airport visibility observations and the regression analysis that relates the weather corrected extinction coefficient to fine mass.

Clusters of urban sites cause traditional inverse distance weighting interpolation of pollutant concentrations to be biased toward urban concentrations. A new spatial declustering method has been developed that incorporates distance and station density to alleviate much of this bias. Sites located within a cluster are assigned smaller radii of influence and are weighted less than a remote site whose area of representativeness is large. The uncertainties in the estimates and interpolation performance are analyzed using the statistical method of cross validation. The newly developed spatial interpolation method has been tested in the mapping of tropospheric ozone concentration data.

The distribution of back trajectory segment endpoints over a latitude-longitude grid is examined as a function of measured concentrations at the fixed monitoring site. Grid cells in which segment endpoints are preferentially associated with high concentrations are then identified as candidate emissions sources. The method correctly identifies southern California as a source of CH3CCl3. An objective rationale is developed for screening out chance associations, attributable to statistical fluctuations, and the results are evaluated for real and hypothetical tracers with known, simple distributions.

Incorporation of related data into the spatial interpolation of fine mass aids the interpolation. This paper describes the methodology used in deriving fine particle maps for the U.S. by using visibility (280 sites) and PM10 data (~1000 sites) as fine mass surrogates. The approach utilizes existing fine mass concentration data as the measured "anchor points" for the derived maps. The higher resolution spatial coverage of the visibility and PM10 networks combined with their relationships to fine mass results in more detailed fine mass maps. Quarterly fine mass maps are derived for 1988-92.

Clusters of urban sites cause traditional inverse distance weighting interpolation of pollutant concentrations to be biased toward urban concentrations. A new spatial declustering method has been developed that incorporates distance and station density to alleviate much of this bias. Sites located within a cluster are assigned smaller radii of influence and are weighted less than a remote site whose area of representativeness is large. The uncertainties in the estimates and interpolation performance are analyzed using the statistical method of cross validation. The newly developed spatial interpolation method has been tested in the mapping of tropospheric ozone concentration data.

Because control strategies for primary and secondary PM are very different, it will be useful to develop techniques for separating the secondary and primary PM components. One approach is to examine the relationship between ozone (as a surrogate for photochemistry) and measured PM. We have done a preliminary examination of this for an 8 year data set in Chicago. Our data set contained daily PM10 (about 95% complete) and 8 hr max daily ozone. We developed a transfer function model predicting current PM10 as a function of previous day PM10, same day ozone and previous day ozone. The previous day PM10 effectively controls for the autocorrelation in the model's residuals. Both ozone terms are highly significant. It is also interesting to note that both ozone terms stay significant when NO2, SO2 and CO are also added. Because secondary PM should be in the PM2.5 size range, the ozone terms in the model with PM10 should be the same as with PM2.5 measurements. The next step is to calculate the effect of a reduction on ozone on predicted PM10. For example, we could 1) predict annual PM10 using the measured PM and ozone records, and 2) predict annual PM10 with a 10 % ozone reduction during the summer high ozone season. The difference in predicted PM should be an estimate of PM reduction due to a 10% ozone reduction in the high ozone season. I will try this to see what happens. Any thoughts on this are greatly appreciated.

Hopefully within the next two years we will be able to learn from/incorporate data analysis/evaluation/assessment results from small scale and large scale field studies, such as the Upper Ohio River study, the SEARCH, and a NARSTO-NE Aerosol study (1999/2000) into the data analysis vortex. I do differ with rich about the focus on data analysis, however. I prefer to think of "this" effort as data assessment..which illicits more of an evaluation context...nit picking again! We have an opportunity to mold a different kind of assessment/thought process. One that has a more univeral flavor of determining the meaning of air pollution data. Transport needs to be universally understood as the linch pin of future assessment efforts...a two way street - how much of air pollutant X comes from an upwind airshed, and how much of air pollutant X leaves my (the) area of concern and influences downwind areas. This is a "us-vs-them" issue. Whenever "we" ask questions on sources and effects "we" need to think INPUT/OUTPUT. This is a "take responsibility for transboundary pollution" issue. If the areas/kinds of assessment are laid out well then the transport wars/issues of OTAG should be reduced. Finally, I would like to see the ozone and PMf data assessment folks merged. ava Submitted by: vanarsdale alan Sumbitter URL: /PMFine/People/people.html#alanvanarsdale Date: 7/24/98 RecID: Forum.alanvanarsdale Comment/Feedback URL: /PMFine/RemoteCFPages/CommentFeedback12.html Workbook - Draft The Ends vs. the Means or the Chicken vs. the Egg?

Submitted by: Heindorf Mary Ann Date: 10/7/98 RecID: Forum.MaryAnnHeindorf The New Website Structure Title: The New Website Structure Description: The website has just gone under extensive revisions. There are now two main section 1) Workgroup and 2) Workbook. Both of which are organized around the 5 workgroups: Status & Trends, Attainment Issues, Source Attribution, Control Strategies, and Resources. The Workgroup sections are the areas where the 5 workgroups work. They include, an Outline that defines the scope of workgroup issues, Resources to be used to create the Workbook content, Project Reports for the proposing, developing and reporting on specific data analysis projects, as well as developing workgroup consus summaries, and a Forum for the free exchange of ideas, questions, etc. The Workbook section will contain the primary Workgroup product, the latest version of the Fine Particulate Analysis Workbook reach by consesus between the members of each Workgroup. The other three section of the Website Activities, People, and Website have not appreciably changed. Submitted by: Schichtel Bret Date: 9/8/98 RecID: Forum.BretSchichtel1 Suggested Website Structure Title: Suggested Website Structure Description: The most timid and aggressive users can be helped by a simple and clear organizational scheme for the Website which we seem to be dancing around. To actually get there we need to know what is the purpose of the web site in the first place. I see this web site as having two purposes. First (or second) to aid in the development of the PM analysis Workbook and second (or first) to house this living and continuously growing workbook. By the way, once the Workbook gets under way it too should be viewed as an aid in its further development. Therefore, the top level of the workbook should contain the supporting materials: Activities, Forum, People, and Website, and the Workbook itself. A suggested outline of the top level is: What's New, Workbook, Forum, Activities, People, Website Such a simple structure will force even the MTU to delve deeper. The Workbook section would then contain all of the PM analysis content, structured according to one (or all) of the suggested forms. Anyone visiting the site, MTU or otherwise, would quickly realize that if they want to view some content they need to go to the workbook section. If we pull any of the Workbook sections to the top level then we added a degree of randomness (in my view) to the website. This randomness will help some first time visitor to quickly find things (inwhich case they may stop exploring), but will also confuse others. No matter what form the workbook eventually takes, I think that we all agree that it must include a Resources section. If we also agree that no Workbook "content" should go at the top level then all resources must be placed in the Workbook - Resource section, or else we would be mixing incompatible elements such as web links and trends at the same workbook level. A suggested structure under Workbook - Resource is: Data, Tools, Literature, Weblinks, Glossary, Contacts (or user groups)??, Training About the Training section. I think that we should maintain the Activities - Training section and place only time sensitive material such as upcoming training events. We should also include a Resource - Training section would contain time insensitive materials. Also, training can go beyond tools, e.g. web sites, so I do not think it should be placed under the Resource - Tools section Submitted by: Schichtel Bret Date: 8/4/98 RecID: Forum.BretSchichtel Suggested Website modifications and enhancements Title: Suggested Website modifications and enhancements Description: With the idea of multiple sort/screen options for viewing workbook content, the need for parallel sections outside "the workbook" seems unnecessary. I wonder if "Training" should also be considered a Resource? - maybe as a subheading under Tools? I think its less an "Activity" of the group, than a "Resource for the individual. "User groups" might be another useful subheading under "Tools", & perhaps also under "data" - maybe even with an automated feature (if feasible) whereby when one downloads a data set or a tool from the site they are automatically added to (or given the option of being added to) the "user group". I wonder if the concept of an e-mail "list-serve" has a place somewhere in the communications hierarchy? While approximately the same function can be served by e-mail distribution lists, the list-serve features of "subscribe" and "unsubscribe" provide a nice option for external entry to or retreat from a particular discussion or user group. For example, the subgroups (trends, who done it, etc.) might be appropriate forums for list-serve discussions. These would not replace the more open web-communication structure, but might fill an intermediate niche (and could perhaps also be made accessible via website through some sort of "news-reader"? Regarding categorization (my NOAA READY submittal as example), some "resources" might have multiple logical categories (for READY, we have "data", "tools" and "training" - & might well add some "literature" and "glossary" links to same (though it could also be simply considered as just a "web-link"). In such cases, it seems "Redundancy" is the way to go - ie have each item listed under each category to which it pertains, with emphasis on the category (ie. the header would emphasize READY data under data, READY tools under tools, etc. Submitted by: Poirot Rich Date: 8/4/98 RecID: Forum.RichPoirot4 Where should the resources go?
