Technical reports and studies 

CAUTION

This site contains presentations reports from various scientific studies conducted to learn more about air quality in the Columbia River Gorge National Scenic Area. Each report adds to our overall knowledge about the Gorge. New studies may reinforce or change the conclusions of previous studies and our understanding of Gorge air quality. Care should be taken to understand the full scope of available research and the current state of knowledge about air quality in the Scenic Area.

If you have questions about individual reports, report conclusions and the current state of knowledge about Gorge air quality, please contact:
