Figure 5

Annual trends of (a) Q₁₀ (raw-Q₁₀) and (b) soil-moisture-normalized Q₁₀ (normalized-Q₁₀). Relationships between the mean annual temperature and (c) raw-Q₁₀ and (d) normalized-Q₁₀. Relationships between (e) soil moisture in the summer (from July to September) and raw-Q₁₀ and between (f) precipitation in summer and raw-Q₁₀. The normalized-Q₁₀ was calculated from F_c data only when the soil moisture content was within the range of annual average ± 1 SD. Regression lines are only presented for statistically significant relationships (p < 0.1).
