Definition
- The Subregional Cooperative Electric Utility, National Park Service and Enviornmental Protection Agency Study (SCENES) was a major long-term observational study conducted by several industry and government groups to understand factors influencing atmospheric visibility in the southwestern United States. Routine measurements were made to relate ambient aerosol concentrations and visibility. Seasonally intensive measurements were made that can be used to characterize regional transport of aerosols and to identify source categories. Data were obtained over almost 6 years at 11 locations. Most of the routine measurements and external auditing were in place at all observatories by mid-1984 and these measurements were terminated or no longer contributed to the central data base after 30 September 1989. The eleven SCENES observatories focused on the national parks, monuments, and recreation areas that stretch from the intersection of California, Arizona, and Nevada along the Grand Canyon and into southern Utah. Data from the Research on Operations Limiting Visual Extinction (RESOLVE) and NPS observatories collected during the SCENES study period have been included in the data base for comparison, but observatories were not operated using SCENES protocols. The RESOLVE monitoring locations in California, which were operated in close coordination with SCENES, are usually upwind of the SCENES sites under the prevailing westerly flow, but could be downwind of the Los Angeles Basin and the San Joaquin Valley, both of which are strong sources of air emissions. Smelters are clustered in southern Arizona and just across the border in Mexico. Power plants are spread across Arizona, New Mexico, Utah, Colorado, Nevada, and California.
