Study on the Response of the Summer Land Surface Temperature to Urban Morphology in Urumqi, China
Round 1
Reviewer 1 Report
Line 13-15, this description is problematic. There are numerous studies on the relationship between 3D morphology and LST. The development of LCZ addresses this issue. Authors have to re-define the research gap and the research aim.
Line 40-41, authors have neglected the impact of urban ventilation performance reduction associated with the increase of building density and height. Please refer the publications on the precinct ventilation zone, and its relationship between urban heat islands and outdoor thermal comfort.
Line 68-71, Please also consider the vertical typology based on the different combinations. Authors must respect local climate zone typology, as well as precinct ventilation zone typology which are important urban morphological schemes.
Line 153, please also showcase the local time (04:56:07).
I am not sure if June 18 can well present summer. Is it representative? Some studies on the monthly variation of LCZ temperature in Shenyang showed that the monthly temperature varied significantly.
In Subsection 2.3, references should be presented since you have presented many equations.
Line 206, please indicate the location of the sensors to record Ta.
Please indicate the limitation of this paper.
Please keep the tense consistent.

Reviewer 2 Report
The article presents scientific and social merit, delving into the analysis and demonstrating the impact of urban form on the formation of heat islands, with an emphasis on three-dimensional analysis, something highly necessary in the field of urban climatology.
The main weakness of the study is that the authors rely on the analysis of a single day of imaging (June 18, 2022). Perhaps an average of summer periods over several years could provide greater data representativity. Nevertheless, this limitation does not invalidate or diminish the article's merit, which is very well-written and well-founded.

Reviewer 3 Report
This paper analyzed the spatial heterogeneity and scale dependence of urban land surface temperature in Urumqi from the perspective of urban 3D spatial form. Furthermore, the influence of 3D spatial morphological characteristics on the spatial variation of LST is discussed by using the geographical weighted regression analysis method. In general, the research method is reasonable, and the research conclusion has certain scientific value for guiding urban planning to mitigate the surface heat island effect. However, there are still two minor issues in this paper that need to be further clarified and revised.
1. In the built environment, there will be correlation between the three dimensional spatial morphological features. In the discussion section, the effects of Building Density (BD), Building Height (BH), Floor Area Ratio (FAR), and Sky View Factor (SVF) on land surface temperature should be discussed on synergy and tradeoffs.
2. In the conclusion section, it is suggested to further summarize the zoning strategy of regulating urban thermal environment according to the spatial heterogeneity of the influence of spatial form factors on land surface temperature.
