Stacked bar density distribution of lake-wide, interannual, Kendall’s rank correlation coefficients between chl-a and LST for 188 of the world’s largest lakes. The significance of the p-value associated with the coefficient is indicated by the greyscale. Correlations between chl-a and LST are highly variable across lakes (i.e. both positive and negative correlations) and strong (i.e. high proportion of correlation coefficients are significant, Wilcox signed-rank test, p < 0.05).
