Table 1. Daily mean air temperature, ozone concentration (12 hours), air humidity, and soil moisture and temperature during the experimental period for experimental climate treatments.
Data are means ± SE (n = 3). CF, charcoal-filtered ambient air; W, warming; eO3, elevated O3; W + eO3, warming + eO3. Significant P values (P < 0.05) are shown in bold, ANOVA mixed model.
