Dear authors,

First, I want to apologize for the long delay of the decision, which was due to the fact that I wanted to give the referees the chance to have a look at the revisions before making the final decision.

I think that the revisions of the paper have largely improved the text and added the required clarifications. However, I would like to encourage you to work on the quality of the figures. Your graphs do not follow scientific standards in all cases. Please, check in particular the axis labelling (axis titles, tick labels) for completeness and consistency. Make sure that all x- and y-axes do have a title (also if it is date or time as in Fig. 7, 8, 9, 11), that the title is located at the bottom or top and left or right (not in the middle as in Fig. 3). Do not put units to the axis labels but to the axis title (compare your height axes!). Adjust the letter size to the figure size (some letters and numbers are very tiny). Check consistency of the use of lower/upper case etc.

Thank you and best regards,
Ulla Wandinger
