Active layer thickness for model results (vertical axis) versus observed ALT values (horizontal axis). The results of the improved (red) and conventional (blue) schemes are shown. The box and whisker plot indicates the minimum, lower quartile, median, upper quartile, and maximum values of observation. The correlation coefficients for the relationship between the model results and the observed data are also shown
