The boxplots (top) show the distribution of correlation coefficients across all grid cells at 10 km resolution, using both Spearman (left) and Pearson (right) metrics. The orange line indicates the median value, and the green triangle indicates the average. The maps (bottom) display the spatial distribution of the correlation values for Spearman (left) and Pearson (right), highlighting generally high and spatially consistent agreement across most of Italy, with local variations in mountainous and coastal areas. All recorded points have a significant statistic with a p-value < 0.01. Basemap: OpenStreetMap contributors.
