"Snow persistence is shown as mean snow cover index, or the proportion of time snow was on the ground from Jan 1 to July 3, 2001-2020". I was expecting it'd instead be average depth of snow (with logarithmic binning). I imagine snow persistence correlates, although nonlinear, and also factors in altitude of each hextile. PS OP's dataset currently doesn’t include Alaska and Hawaii
