You have addressed the suggestions of both reviewers. I think the manuscript is acceptable for publication. However, before that I do suggest the following small edits (page and line numbers refer to the change-tracked version of the manuscript):
Page 1, line 13: replace slight by small
Page 1, line 14: replace unique by important
Page 2, line 2: replace since by due to
Page 2, lines 14/15: delete "caution is needed for" and replace "to" by "are needed to"
Page 2, line 22: replace which by when it
Page 3, line 12/13: delete "generated by two emittter lasers" (It could also be one laser, e.g. a dye laser)
Page 3, line 28: replace "energy" by "intensity" (return signal are not energy, they are energy/time = intensity)
Page 6, line 22 (and everywhere else): replace color-scaled by color-coded
Page 7, line 27: replace "The difference ... the sPV" by " Ozone changes are related to the sPV"
Page 10, line 7: replace "between than" by "than with"

These were just a few examples for editing. ACP will probably copy-edit the text. This should improve clarity / english further.
