Suggestions for revision or reasons for rejection

I would thank authors for the effort in revising the manuscript and I would highlight some minor comments that could increase the readability of the manuscript to a not-specialized reader.

Figure 3 Please show dates in the x-axis of panels 3a and 3b, the x-axis of panel 3c can confuse the reader since the number 12 (December) could the the beginning, the middle or the end of the month...

Figure 5, there is a lack of data in December? Please specific in section 2.3 line 27 the date and fix the dates in x-axis of figures 3,4,6-11. Fig. 3-4 winter (1 Dec - 28 Feb), Fig.7-10 spring (1 Mar - 31 May), Fig. 8-11 summer (1 Jun - 31 Aug) and Fig. 6-9 autumn (1 Sep – 30 Nov).

Figures 3,6-8, I should be able to connect easily the defined variables to the text of section 2.3.1… While from figure 3a I find CRn-observed, CRn-advected and CRn-subtracted, in panel 3b I read CRn-synoptic and CRn-diurnal. These variables are cited in the caption but they cannot be found easily in the text:

is CRn-observed cited in page 6 line 36?
is CRn-advected cited in page 7 line 16? I’m pretty sure and I ask to indicate the variable there...
is CRn-subtracted cited in page 7 line 29? Yes, please use the same symbol (substracted CRn or CRn-subtracted)
is CRn-synoptic cited in page 7 line 30? Yes, please use the same symbol (synoptic CRn or CRn-synoptic). I understand also that “synoptic” = “advected” - “subtracted”...I think that the declaration of synoptic could be supported by an equation...Please change the color of synoptic in figure 3 and similar...It can be confused with advected…
is CRn-diurnal cited in page 7 line 11?

Figure 3b authors show +σ (CRn-diurnal) in the legend and then σ just above the dashed line, I think they are the same….Call them in the same way or remove σ and indicate only the value…

Pay attention to σ and μ in Figures 3,4,6-11 since σ and μ are described also in page 7 line 31 and page 9 line 17

P1 Line 12 … new radon-based method (RBM), based on single-height 222Rn measurements…

P4 line 27 what do you mean with “(±25%; Jacob et al 1997” ? Radon emanation in the Earth crust?

P5 line 10 Julian and Kamnik-Savinje Alps?
