Additional figure that shows the rural reference sites that were used to calculate the urban heat island intensity

Response—Figure C1 at the end of the document shows the location of all the rural sites used to calculate the urban heat island intensity. These stations were operated by the National Weather Service (NWS): the call letters used in the figure match the NWS' station id. The location and the elevation of the sites are: KFRG (40.73443, 73.41639, elevation: 22 m), KISP (40.79389, 73.10167, elevation: 30 m), KMMU (40.8, 74.41667, elevation: 57 m) and KMGJ (41.50917, 74.265, elevation: 110 m).

Corrected caption for figure 3 (Comment The legend provided in figure 3 does not correspond to the actual contours that were plotted.)

Response—Figure 3 shows boundary layer profiles of potential temperatures. In the top row, the brighter lines indicate data obtained from heatwave events at four stations, each with a distinct color, and the lighter-toned lines are from the same four sites but for normal non-heatwave days. The bottom two plots show the difference in nighttime and daytime potential temperature profiles from two sites for heatwave and normal days. The legend shows the colors and the shades.

Corrected caption for figure 5 (Comment First, the caption of figure 5 does not specify the temporal inconsistency between the top and bottom panel.)

Response—Top panel in figure 5 compares indoor and outdoor temperatures from 8 to 31 July 2016: the indoor temperatures were not available for 1–7 July. The bottom panel shows the surface soil moisture and precipitation for July 2016. The heatwave events are marked by rectangular boxes in the top panel.

Addressing the inconsistency in naming the heatwave episodes referred to in the text and the figures (Comment 'In figure 4, heatwave 1 is shown as roughly occurring between 5–9 June and heatwave 2 as occurring between 15–19 June (referring to labels on the figure panel). This is inconsistent with what is presented in figure 5, where temporal definitions of the heat waves are completely different. The labeled heat waves do not coincide in time though the text refers to them, collectively, as 'heatwave episodes'. Second, the heatwaves labeled in figure 5 are not temporally consistent with the heat waves labeled in figure 4. Figure 4 details a heat wave occurring on 5–9 June and most of this period is omitted from figure 5, though it is unknown why)

For the location of urban stations, refer to figure 1.

Response—The authors are aware of the inconsistency in naming the heatwave episodes- the heatwave episodes shown in figure 4, are from 5 to 9 July and 15 to 19 July 2016. The data shown was obtained from the microwave radiometer. The heatwave episodes referenced in figure 5 lasted between 15–19 July and 22–26 July 2016.
