I am happy to communicate that both Referees have found significant improvements and only have a few minor comments left, which I ask you to address fully. I am looking forward to review the next and hopefully last revised version of your manuscript.

Dear Authors,

I am confident that your manuscript can soon be published after consideration of my following Editorial comments:

1. Abstract: check that all statements and numbers are up to date.
2. Section 3.2.5, comparisons with other emissions estimates: You have to clearly state that your values stem from a single mass Balance measurement on one particular day, and time of day. Consequently the representativity of your measurement is very limited. Your sampling uncertainty may likewise be high. They are not included in the error you indicate.
3. Figure 3: The figures 3 c,d,e,f are very questionable and may mislead readers. They cannot be published. Figure 3b is enough to explain the issue of strongly diverging results below the lowest measurement level. Remove figures 3 c,d,e,f.
4. Figure 5d and e: the aspect ratio is about 1:100, the figures are stretched vertically by about a factor 100. Mention this in the caption.

Please provide a hopefully final version incorporating all these points.
Kind regards, C. Kiemle
