Fig. 4: Analysis of absolute albedo change and relative albedo change at PV sites across different land cover types and climate regimes.

a The ratio of site numbers in specific climate regimes to the total sites of corresponding land cover types. WB, Ba, Cr, OS, Gr, Sa, and Wsa represent sites with the background land cover of water bodies, barren, croplands, open shrublands, grasslands, savannas, and woody savannas, respectively. Additionally, the nomenclature following each land cover type signifies the climate regimes, which are derived from the Köppen–Geiger classification map, and more details are shown in Supplementary Table 5. Only groups with a site number exceeding three are depicted in this figure. b, c The box plots of albedo change (×10−2) and relative albedo change compared to the background albedo, respectively. The white center line of each box represents the median; box limits represent the upper and lower quartiles; whiskers extend to 1.5 times the interquartile range. Captions near the box plot show the median and interquartile range (IQR) of corresponding categories, respectively.
