Figure 2. Coefficients of the MLR regression analysis describing unique changes in air temperature with changes in urban fraction.

Figure 2

a, Probability of seasonal occurrence of four aggregated phenological phases. b, Seasonal variation of MLR coefficients (βUT; Eq. 2) for three urban fraction (UF) metrics (COR … CORINE land cover, IMD … imperviousness degree, ESM … European settlement map; mean and ± one standard deviation). c-f, Boxplots of MLR coefficients (panel b) weighted by probability of the four aggregated phenological phases (panel a). Significant (p < 0.05, Wilcoxon rank sum test) differences between urban fraction metrics are indicated by the same letters. Boxplots show the interquartile range (IQR, box), the median (horizontal line in box) and 1.5 x the IQR (whiskers), while outliers are omitted for clarity.
