The reviewers are basically satisfied with the revised manuscript. However, I have a few sugestions before the manuscript can finally be accepted for publication by The Cryosphere:

1). What are the dashed-lines for in Fig. 2 and 3? By reading the figure caption, the readers cannot know what are these dashed lines for. The authors need to add more text in the caption to explain. If these dashed lines are linear trends, the authors need to show the significant test value (p value) and correlation coefficients.

2). Figure 3: suggest after (a), (b), (c), and (d), add winter, spring, summer, and autumn, respectively.

3). Figure 4: the scale is too coarse. Suggest to remove the scale for snow covered days more than 180 days and expand the remaining.
