Dear Authors,
As you can see and has responded already, the comments raised by the two Referees are very constructive. Your response to the comments are clear and meaningful. I suggest that you revise the manuscript thoroughly and submit for further review.
The following are my comments, which can be considered together when you revise your manuscript.
1) L42-43, please use the full names of these transboundary rivers. For example, Mekong should be Lancang-Mekong.
2) L104, thaw should be thawing? please check.
3) L177, you only get the monthly meteorological data?
4) L211, Section 2.3.2, it is interesting to use baseflow separation method to quantify active groundwater storage. I understand the method is adopted from literature(s). But we cannot clearly see this from current description of the method. It seems to me that the method is more like a new (at least a modified) method. Please check and revise the description accordingly.
5) L306, it is interesting to know summer meltwater partly infiltrates into soils and will be stored in aquifers. But in this paragraph this point shows up suddenly. It is better to add more sentences to discuss. I know it is difficult to obtain measured data for underground things, but still we need more deep/logical explanations. Also, in my opinion it can be stated as a hypothesis.
6) L369-370, similar to comment 5).
7) L399, I suggest to use same unit (mm) for total glacial value (decrease).


Best,
Editor

Dear Authors,
I got the comments from two Referees. I understand the field experimental data in Tibetan Plateau is really rare and valuable. I suggest the authors to address the following comments (repeated from the reviewer's comment):
1) To elaborate the mechanisms of hydrological processes, hydrological cycle and the relations between recharge and drainage in alpine region.
2) To elaborate the main source of streamflow.
3) Revise Figure 3.
4) Try to use more data in this paper in available.
