Dear authors, your manuscript will be published after you consideration of a few minor remarks of mine.

1. Please put a legend on figure 1. I am not sure if people which are not from Europe will immediately see, where you operated. The same is true for panel a in figures 5 to 7 and subpanels h and g in figure 11. I know that this is more or less double information, but in my view it would make it easier to read and to concentrate on the contents of the paper rather than geography.

2. In figure 8 you explain what you mean with arrows at the colorbars, but you seems to use them in figures before too. Or is this a misconception?

3. The abstract and the conclusion are often read first to assess if the manuscript is interesting (for the particular reader not in General). It therefor enhance readability if the abstract and conclusion can be read independently from the main text. In order to do so, I suggest:

You use the abbreviation LMS with expanding it again. LWS seems to be a rather unusual term, so it would enhance readability to mention it again. Also, please write measurements from the GLORIA instrument (instead of measurements from GLORIA).

In line 12 of page 27 you write '..Although ozone loss was greater in 2010/2011, 2015/16 was a winter with extraordinary large chemical ozone loss. ...' This left me wondering if there are other 'types of ozone loss' and what they are. I think most people would equate 'ozone loss' with 'chemical ozone loss'.

Kind regards
Mathias Palm
