Impact of livestock activity on near-surface ground temperatures in Mongolia
Abstract. Grazing by livestock can alter the surface conditions at grassland sites, impacting the transfer of energy between the atmosphere and ground and consequentially ground temperatures. In this study, we investigate surface cover in summer and winter and measure ground surface temperatures over 14 months at sites in Central Mongolia that feature different grazing intensities (intensely and ungrazed) and topographic aspects (north- and south-facing). Overall, intense grazing leads to a substantially reduced vegetation cover, altered snow conditions and lack of surface litter accumulation. Comparing intensely grazed and ungrazed plots shows large seasonal differences in ground surface temperatures, with grazed plots being up to +5.1 °C warmer in summer and −5.4 °C colder in winter at a south-facing site. We find smaller seasonal differences of +1.4 °C and −2.5 °C between grazed and ungrazed plots at a north-facing site which receives less solar radiation and where differences in vegetation cover between open and fenced plots are smaller. For both aspects, the seasonal differences largely offset each other, with both a small net cooling and warming depending on effects in spring and autumn. Our study suggests that livestock management might be used to modify the annual ground temperature dynamics, possibly even influencing local permafrost dynamics.

RC1: 'Comment on egusphere-2024-1790', Anonymous Referee #1, 21 Aug 2024
The above-mentioned article focuses on a topic that has received little attention to date, namely the influence of intensive grazing by mobile livestock farming (1), the effects on vegetation (2) and on the soil (3) as well as the resulting changes in permafrost (4). This is demonstrated in two local examples using series of measurements over a period of 14 months in two different exposures.
However, the title of the article is misleading in that the reader would expect generally valid statements for the whole of Mongolia. I would therefore strongly recommend adapting the title accordingly and also pointing out the limited duration of the measurements.

This paper discuss the grazing impacts on ground thermal conditions using onsite ground surface measurement, and snow and vegetation surveys. Writing style is well organized and text is understandable. Also the author's discussion and conclusion are consistent with the measurements, then I would recommend this acceptance after following revisions.
Methods
Resolution of GST measurements: the sensor accuracy is 0.5degree, is this enough to support your discussion?
Your open site is just outside of the fence, where snow accumulation could be influenced wind disturbance of the fence and differ from site far from the fence.
Can you show the location of vegetation, LAT and snow surveys on the map(Figure 1) ?
Snow was measured only in one day. Did snowfall. clearing animal footprints, occurr before this day?Results
Consider the difference in daily cycles of GST at fenced and open sites?

L248 doubled 'Figure9'Discussion
L313-320 This part is just summary of previous chapter, and could be shortened or omitted.
L335 could be 'Grazing and snow impcat on ground surface temperatures'
L364-366 Do you have any image of snow condition such as onsite photo or satellite image?
