Technical corrections

p. 1, l. 23: exerts a strong impact -> exerts a strong influence OR has a strong impact

p. 2, l. 2: and almost doubled compared to the rest of the globe -> and was almost twice as strong as the global average

p. 2, l. 20: and THE active layer

p. 5, l. 5: "The left side of the equation represents the system’s gain of energy and the right-hand side represents the losses of energy." This is not always so? For instance, Rnet is energy loss during the polar night. If you mean this for period average, then please state so. Also please make clear how the signs of the SEB components are defined.

p. 6, l. 11: equals to -> equals (?)

p. 6, 3.1: Obviously these slopes are significantly smaller than 1. State that this will be discussed in section 4.

p. 7, l. 14: "The average air temperature, which mainly controls the downwelling longwave radiation..." this is only partly so; emissivity (cloudiness, humidity) also is important. See also next remark.

p. 7, l. 15/16: " the snow surface temperature together with cloudiness". There appears to be a mashup of information here, please check.

p.7, l. 21: mainly driven due to -> mainly driven by
