Individual Class I Area Reports The individual Class I area reports combine monitoring, modeling, and emissions data, and associated analyses, for all WRAP federal and tribal Class I areas.

Regional Aerosol Mass and Extinction
The following link leads to maps which depict the average IMPROVE mass and extinction (by species), deciview, and standard visual range of the 20% worst days monitored in the WRAP region in 2002. These products are similar in style and content to what is available for the entire U.S. on the VIEWS Web site, but were modified to include only data from 68 western IMPROVE monitoring sites. Since no data from urban monitoring sites were included in the generation of these products, the results should be interpreted for wilderness areas only. (All maps were generated by Rodger Ames of CIRA.)

Regional Emissions
The following link leads to maps which depict the 36x36 km gridded emissions summaries for the CMAQ modeling domain. Maps are available for NOx, SO2, VOC, NH3, PM2.5 and PMC emissions, displayed in tons/year. Emissions for each grid cell on each map represent summations from categories including point, area, mobile, dust, fire and biogenic sources. These maps display the interim emissions used in Phase I of the AoH project. Links to detailed emissions inventories can be found under Emissions Inventory Information below.
