Incorporating Monitoring, Modeling, and EI Data into AoH Analysis AoH Meeting, Salt Lake City September 21-22, 2004 Air Resource Specialists, Inc.
2
Regional Analysis AoH Phase I intended to make assessments that cover broad regions Many Methods of approaching regional/cluster analysis –Similar aerosol composition –Similar emissions source regions/categories –Similar geography –Similar meteorology
3
Regional Clusters on COHA Website COHA: http://coha.dri.edu/web/general/trajgallery/trajmapgallery.htmlhttp://coha.dri.edu/web/general/trajgallery/trajmapgallery.html
4
IMPROVE Particulate Monitoring Cluster Criteria All Class I areas within 100 km of a current site Site location lies between highest and lowest elevations of all areas in cluster 156 Class I areas combined into 108 clusters
5
IMPROVE Clusters IMPROVE Sites Class I Areas
6
Look at CMAQ-TSSA results and group sites that are basically influenced by the same sources Look at trajectories of the 20% worst visibility days and group sites with similar patterns Look at monitoring results Possible Expansion of IMPROVE Clusters

DRI residence time maps and trajectory regression analyses Temporal Resolution of Aerosol Data –Total Extinction –Mass –Worst and best days Summary of particulate and visibility data, and attributable emissions What else would be helpful for States and Tribes for Phase I? Other Tools for Attribution Analysis
