Tribal Assessment: Phase II
|
Conclusions |
|
As a result of this effort we have
provided a tool for which tribe may be able to select an appropriate IMPROVE
site from a site in the region for use as representative of visibility.
However, the recommendations provided in this report for represenatative
sites are not meant to be used without a careful examination on an
individual basis. |
|
The best use of results from this project
will be to utilize the tools in each task in a sequential order in order to
uncover an appropriate site for visibility. Results from this effort provide
at least one or more possible represenatative site even if not represented
in the first or second task. |
|
Results of this project are assembled in
a virtual report on the Causes of Haze (COHA) website, http://coha.dri.edu.
Access to the Tribal reports can be accessed through the link on the left
hand side of the website. The COHA website serves as a platform to integrate
and present results in concise and understandable language that can be used
to support regional evaluations of and justification for actions that
improve western visibility. The website allows access to the virtual reports
using multiple pathways. Users can simply select a site of interest using a
map or from a list of sites. Other methods of accessing the reports are
thematically based on regions, similarities in aerosol composition or
meteorology. From various hyperlinks, a user can view descriptive analysis
discussions on aerosol composition, the emissions surrounding each site, the
physical terrain, and meteorological conditions. Other specific products of
this project are have been used to help determine what is causing haze are
air mass trajectory maps, maps of emission sources that include point, area,
mobile and biogenics, terrain and landuse maps, satellite images, and maps
showing locations of urban areas. |
