Dear authors,

I am pleased to inform you that your paper is accepted for publication in ACP after consideration of the minor technical corrections given below:

- P1, L22: skip " hereafter L12" and write in the following Lambert et al. (2012) instead of L12.

- P2, L6: Same as above for Pitts et al. (2013). Using the reference itself instead of the abbreviation is much easier to read.

P8, L17: "kelvin" ----> "Kelvin".

P11, l30: Typing error in "Höofner" should be corrected.

P18, 29: adquetaly ---> adequately.

P19, l13: Please give the full reference, thus add the year to the reference of Höpfner et al.

P20, l8: One closing bracket is obsolete.

Best regards, Farahnaz Khosrawi
