Incorporating Monitoring, Modeling, and EI Data into AoH
Analysis
AoH Meeting, Salt Lake CitySeptember 21-22, 2004
Air Resource Specialists, Inc.
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
Regional Clusters on COHA Website
COHA: http://coha.dri.edu/web/general/trajgallery/trajmapgallery.html
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
IMPROVE Clusters
IMPROVE Sites Class I Areas
• 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

Monitoring Results
• July and January, 2002 preliminary results presented at July, 2004 AoH meeting– 1st look at site groupings:
• July• 20% worst modeled extinction days• NOx
Rocky Mountain National Park CMAQ-TSSA NOx
Mount Zirkel WA CMAQ-TSSA NOx
White River WA CMAQ-TSSA NOx
Trajectory Analysis
•HYSPLIT calculated back trajectories matching July 2002 days from modeled data
Model Parameter ValueTrajectory duration 72 hours (3 days) Top of model domain 14,000 metersVertical motion option used model dataReceptor height 500 meters
•EDAS meteorological data was used for trajectoriesNote: CMAQ modeled data uses MM5 meteorological data

Monitoring Results
• IMPROVE aerosol samplers– 24-hour integrated aerosol sample every 3
days– Analytical results can be characterized by
visibility contribution of individual species

• 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?
