(a) Spearman correlation coefficient strength as a function of wavelength for the total (global), maria, and highlands trends. The maria show a consistent correlation at all wavelengths of reflectance with latitude. The highlands show a variable strength correlation of reflectance with latitude, with the strongest correlation in FUV. (b) Statistical significance of correlation as a function of wavelength for the total (global), maria, and highlands trends. Data are shown in log scale. All regions show greater than 3σ significance.
