Regional variability in the lake-wide, interannual, Kendall’s rank correlation coefficients between chl-a and LST for 188 of the world’s largest lakes. The size of the dot is proportional to the significance of the correlation. The color of the dot reflects the magnitude of the correlation. The map was made using R version 3.3.355 (https://www.R-project.org). Land mass polygons are from an open-access digitial map in the package “ggmap” (https://github.com/dkahle/ggmap).
