Dear Cristina,

I'm pleased to accept your revised manuscript "Discrete-wavelength DOAS NO2 slant column retrievals from OMI and TROPOMI" subject to minor corrections as listed below. Please also take note of the revision suggestions made by one of the two reviewers.

Best regards,

Andreas
================================================================
1) In the discussion of the interpolation of the radiance spectra, two things should be noted:
a) F_0 is the high resolution irradiance, convoluted with the instrument slit function
b) applying this scheme to radiances instead of irradiances is problematic as the shape of
the Fraunhofer lines changes as result of rotational Raman scattering in the atmosphere

2) I agree with the reviewer that the large scatter in your global correlation plots is probably due to the SAA. It would be worthwhile to filter the data before creating the scatter plots as these fits are not expected to be good.

3) Please make sure that figures 4, 6 and 8 use the same logic with respect to choice of what to plot as x, and what as y-axis

4) In several places, the discussion of vibrational Raman scattering contains the formulation "over water". While I assume that you refer to the fact that measurements over water are affected by this signal, it still could be misunderstood as vibrational Raman scattering in the air over water instead on water molecules within the ocean
