Thank you for taking into consideration my comments/suggestions and those from other reviews. As a result, the paper is now much clearer and easier to read. Below you will find some more specific and technical comments that I hope you will find useful.
Line 36: “complex local factors”, could you give one or two examples?
Line 94: temperature: could you give the range and also the mean for a specific time period, e.g., 1990-2020? Could be something like “The mean annual air temperature for the 1990-2020 period ranges from -5 to 5°C (mean = -2.4°C).
Line 101: You mention that permafrost has formed extensively, but could you specify if it’s continuous or extensive discontinuous?
Line 332-333: Do you not report DDF in negative values? According to your definition, they should be. You should either mention at the beginning (line 133) that DDF are in absolute values to facilitate comparisons with DDT, or change in the text for negative values (and change figures like Fig. 3) accordingly.
Line 449: Could you add an example of “thermal perturbations”? E.g., “highly susceptible to thermal perturbations such as a warmer summer”.
Line 458: “showed fewer permafrost areas”, is this compared to the local survey map or compared to the Wang map? Please specify.
Line 56: remove “that require sufficient accuracy”
Line 92: The coordinates both indicate East, change one for North
Line 92: Change the sentence to “The QTP (bounded within 73.5–104.5°E and 26–40°N) is a high-elevation flat terrain of about 2.6×106 km2 surrounded by surrounded by high mountain ranges (Fig. 1).”
Line 95: remove “in most areas between 3000-5000 m a.s.l.”
Line 96: Change “In the last five decades preceding 2010” to “From 1960 to 2010”
Line 97: Change to “Mean annual precipitations decrease from more than 700 mm in the southeast to about 50 mm in the northwest, and about 90% of precipitations fall during the growing season from May to September”
Line 99: Move this sentence to the beginning of the section, I suggest as the second sentence, right before “Most of the QTP lies between…”
Line 101: Change sentence to “Alpine permafrost has formed extensively on the QTP (ADD SOMETHING ABOUT CONTINUOUS/DISCONTINUOUS). Ice-rich layers are often found near the permafrost table, which is generally 2–3 m deep (Zhao et al., 2020).”
Line 158: Change times to “2:00, 8:00, 14:00, and 20:00” and remove o’clock
Line 165: could you list the three sources with first, second, third to facilitate reading? E.g., “First, a newly published […]”, “Second, seven boreholes were collected […]”, and “Third, in the Yangtze River […]”
Line 202: remove “where DDF and DDT represent annual ground surface freezing and thawing indices (°C∙day), respectively”, already defined earlier in the text, you could directly explain E.
Line 239: Change beginning of paragraph to “Conversely, vegetation cover affects DDT by providing a strong […]”
Line 265: Remove “Since there is no simple way to determine wk and wb”
Line 301: Remove “(Zou et al., 2017; Wang et al., 2019)”, since you defined the names of the map from those references, you don’t need to cite them every time (like in the next sentence). To correct everywhere.
Line 311: As in my previous review, this type of sentence describing the figure should be avoided in the text, I suggest you go directly in what you want to say, e.g., “In-situ DDT (DDF) was compared with raw-LST-derived DDT (DDF) to determine the fit of the model (Fig. 3).”
Line 323: Could you replace “below the 10% level” with something like “below our accepted level of error (<10%)”, otherwise this information is useless.
Line 403: Please add the percentage cover for non-frozen ground to be consistent with the rest and facilitate reading.
Line 422: End sentence after (Fig. 9). Then, start a new one “Our map had a Cohen’s Kapa coefficient of about […]”
Line 453: Change “For the Wang map” to “Since the Wang map”
Line 455: Change sentence to “Together, all of these factors caused the Wang map to overestimate permafrost extent in Gaize”
Line 465: Table 4, should it be Table 3?
Line 479: Change decent to statisfactory
Line 501: Change “terrain, vegetation, soil properties and so on” to “e.g., terrain, vegetation, soil properties”
Line 522: Remove “especially”
Line 572: Change to “The red boxes in a) and b) cover two boreholes of […]”
Line 580: Change “Our map proved to be more accurate” to “Our map was more accurate”
Line 593: Change sentence to “Despite the better performance of our map compared to other available products, our mapping approach had limitations and left room for potential improvements”
Line 594: Change “leveraged” to “extracted”
Line 635: “In typical regions with distinct differences”, to rephrase, I’m not exactly sure what you mean.
