Lines 92-93: Is it Universal Coordinated Time (UTC) or the university? That must be a typo. Check?

Lines 98-101: The figure 1 caption describes the locations of meteorological and glaciological observations since 2010, denoted by a plus (+). But no mention is made of the installed AWS in the Everest expeditions either, although it is in the legend with some symbol.  

Line 106: Could not find the supplementary information for the photograph links, although it is mentioned.

Lines 127-128: Is there any reason why the AT and RH sensors are installed 1.5 m from the ground for higher AWSs, whereas 2 m for the lower AWSs?

• Will not the heavy snowfall during the events affect the sensors while setting it to a lower level of 1.5 m in higher?

Lines 156-158: Is there any standard time to capture the photo? Why is it set at 0937 NPT and 1437 NPT?

Table 1: What does the 'present weather sensor’ work for?

Section 2.1: AWS details and measured variables

• Why does the manuscript in section 2.1 only elaborate on six variables? Table 1 reveals other sensors, too, such as the present weather sensor and the relative surface elevation change.

Line 180: Supplementary Table S1 could not be found.

Line 201: Supplementary Figure S1 could not be found.

Line 206: What about data availability on surface elevation change or snow? Three sites have these sensors (ref. Table 1) As it would be very useful for the mountaineers and other communities.

Line 212: Average annual precipitation? If it is annual precipitation, 'of which year'?

Line 221: Is it ‘mean monthly’ or ‘monthly mean’?

Lines 226-228: Do the precipitation comparisons between the PH, BC and Pheriche, Pyramid cover the same time frame? If yes, it is not mentioned. Also, two values of precipitation amount from the Pyramid station – what do they mean? Are the values from the two stations at Pyramid?

Section 5: The SC-observed data is compared with ERA5; it is better to give a short overview of ERA5. Why is it not compared with any other stations?

Lines 254-255: As the comparison between ERA5 and observed has an approximation of R² > 0.6 (for all variables) for the period of monsoon and post-monsoon (June to Dec). Are the comparison limits for all seasons due to missing data?

Lines 257-258: Supplementary Figures S3 and S4 could not be found.

Lines 280-282: The wind and gust speed were highlighted for the mountaineers for the period; the comparison was missing for April and May (spring expedition).
