Projects
As described in the organizational charter, NW-AIRQUEST operates as a collaborative effort to share information and resources related to advances in measurements and modeling of air quality in our region. These efforts take place through specific studies initiated through normal agency contract procedures and through more general projects where funding is obtained from outside sources (national grants) or from regional EPA funds. In either case, discussions are held monthly by phone to review progress, discuss specific technical problems, and to share results among all of the NW-AIRQUEST participants. The following is a list of recent and current projects that are routinely shared in this manner. To a large extent, each of these projects share the common use of MM5 as a weather model and, in most cases, the use of the SMOKE emissions processing system to supply appropriate emission inventory data files. Transport and chemistry modeling are typically addressed using either the CALPUFF model or the EPA Community Multi-Scale Air Quality Model (CMAQ).

Nez Perce Project (overview) |
The deposition of nitrogen, sulfur and toxic compounds such as mercury and the resulting ecosystems effects is an emerging issue in the Pacific Northwest. Atmospheric deposition results from local, regional and global transport, and transformation in the atmosphere but the effects of the deposition are seen in surface water and ecosystems. Because these problems cross political boundaries and affect multiple media, they often fall through the cracks of the regulatory framework. The purpose of this workgroup is to provide a regional forum for atmospheric deposition issues, to foster coordinated scientific information sharing between monitoring, modeling and emission inventory efforts in the Pacific Northwest, and to explore connections with the research, resources and needs in other media, including water and biota. |
