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.
