In this work, the nocturnal cooling effect of urban parks within Paris is investigated using an excellent suite of measurements, which allows the authors to concurrently examine the meteorological conditions of the surface and lower atmosphere. Three stability regimes are identified, quantified, and their implications are summarized. The meteorological factors are put in context both spatially and temporally throughout the night. The manuscript has clear motivations and implications, is logically organized, well-written, and includes appropriate figures. There are only a few minor comments.

The lowest gate (~240 m AGL) is used for the vertical variance, but in Fig. 6e/7e it appears to be either at an inversion base or perhaps just above it in these examples. Is there potential that being just below or above the inversion base would have a significant impact on the analysis or conclusions? Although the limitations of the instrumentation prevents measurements closer to the surface, it might be good to at least comment on this point since any measurement near a sharp change of temperature gradient could have large differences just above or below.

Related to the lowest gate, it is given as both 238 and 240 m AGL in the text, but please just select one to be consistent (either the 238 or the rounded 240).

Soil moisture is mentioned around line 742, but given the impact it could have on heating/cooling processes associated with the park, it might be beneficial to comment on this earlier. Specifically, it should be stated if this period was during wet, normal, or drought conditions, and also if these parks are irrigated.
