Felker-Quinn E . 2025. Current and Historical Metrics of Vegetation Ozone Exposure. National Park Service
This R script and the attached methods document will support the user in calculating ozone exposure metrics that describe risk to vegetation from ambient ground-level ozone. The script allows the user to download hourly ozone data from the US Environmental Protection Agency's API and calculate W126 (by current NPS method or by historical FLAG 2000 method), SUM06, AOT40, N60, N70, N80, and N100.
