Cumberland Piedmont Network (CUPN) Natural Resource Condition Summary Table for GUCO Air Quality

Cumberland Piedmont Network (CUPN) Natural Resource Condition Summary Table for GUCO Air Quality. Created by Johnathan Jernigan, Physical Scientist, February 2014.

Ozone Condition: Green ≤ 60 ppb, Yellow 61–75 ppb, Red ≥ 76 ppb. Foliar Injury Condition using W126 Statistic: Green ≤ 7 ppm-hrs, Yellow 7-15 ppm-hrs, Red ≥ 15 ppm-hrs. Foliar Injury Condition using Kohut Assessment: Green is Low Risk, Yellow is Moderate Risk, Red is High Risk Foliar Injury Condition using CUPN Foliar Injury Monitoring: Green is 0 Species Found with Injury, Yellow is 1 – 2 Species Found with Injury, Red is ≥3 Species Found with Injury.
