Air Quality in National Parks

The latest NPS air quality data trend analysis report shows visibility, ozone, and atmospheric deposition conditions and trends for 1998–2007 and indicates whether or not individual parks are meeting NPS strategic air quality goals. The report shows 99% of parks show stable or improving visibility, 94% have stable or improving ozone concentrations, and 83% have stable or improving trends in atmospheric deposition. While improving trends certainly show progress, a stable trend in air quality may not be sufficient to protect an area already experiencing poor air quality.
