Please respond to the following comments and revise.

----------

(1) The description of the slit function used for the calculation of the cloud LUT is still hard to understand (P9, L2). I suggest replacing
“by a 0.88 nm wide (corresponding to 5 pixels 0.22 nm apart), flat-top slit function with a half-gaussian with a Half-Width-Half-Maximum of 0.27 nm at each end.”
with:
“by a 0.88 nm wide (corresponding to 5 pixels 0.22 nm apart), flat-top slit function with Gaussian tails, which have a width of 0.27 nm at half maximum.”

(2) As suggested, the authors added a short paragraph summarizing the difference between the UV algorithm currently used for the processing of OMI observations and the new algorithm to be used for TROPOMI. The second sentence (P4, L7) of the new paragraph sounds a bit awkward and I suggest replacing:
“As regards radiative transfer calculations and Look-Up-Table (LUT) functionality, the TROPOMI UV algorithm is based on the AC SAF OUV algorithm, while other parts of the algorithm are mostly based on OMI.”
with
“Radiative transfer calculations and Look-Up-Table (LUT) functionality of the TROPOMI UV algorithm are based on the AC SAF OUV algorithm, while other parts of the algorithm are mostly based on OMI.”

I also suggest to replace “wanted” with “desired” on P4, L14.

Thanks for your efforts to take reviewer's comments/suggestions into consideration. I would like to ask the authors to review sentences carefully for the last time, before publication.
E.g. p.3 : 12-13, given as input the measured reflectance --> given as input 'with' (or 'from'?) the measured reflectance...
