Figure 2: Heat load index across slope aspects.

The horizontal line in each box is the median, the box endpoints represent the 25th and 75th percentile values, the whiskers represent the non-outlier range, and the asterisks and open squares indicate outliers and extremes, respectively. Differences across aspect classes were evaluated using Kruskal-Wallis H (KW-H) test. Aspect class: 1: shady aspect; 2: semi-shady aspect; 3: semi-sunny aspect; 4: sunny aspect.
