Dear Sebastian Wolff,

I'm pleased to accept your revised manuscript "Determination of the Emission Rates of CO2 Point Sources with Airborne Lidar" for publication in AMT subject to technical corrections. As most of the reviewer's comments have been addressed, I only have a couple of small suggestions to consider:

L11: "weighted vertical columns of CO2 mixing ratios" - I'm confused by this formulation. To me, the result of the measurements are vertically averaged CO2 mixing ratios, not columns

L95: molecular, absorption => molecular absorption

L107: "Δσ(z) is the difference between the absorption cross section of the two laser pulses given in square meter" - not entirely precise as the cross-section is the one of CO2, not of the laser pulse and the difference is because of the difference in wavelength. What about "Δσ(z) is the difference between the CO2 absorption cross section for the two laser wavelengths given in square meter"?

L107: Cross-section is not explicitly mentioned in the Figure, just "absorption"

Caption Figure 4: "and horizontal spacing of 250 m and 50 m" - not sure how to interpret this

L228: Errors according to => Errors resulting from

L230: need not be => need not to be

L242 and elsewhere: two-tenth: I find this way of separating the error into its components quite unusual, why not say "20% of the uncertainty..."?

Section 4: I'm not sure what the right way of determining the mean wind in the model results really is. For a realistic comparison to the measurements, the right wind would be that of the model run at lower resolution. I would assume, that strong turbulence will lead to strong fluctuations in wind speed and direction over time and altitude, and in a real world application, this will further increase the uncertainty of the assumed wind vector and thus the emission estimate. My concern is, that by trying to find the best wind vector from the simulation, the uncertainty is actually underestimated.

L373: higher number of crossings are required => larger number of crossings is required

Best regards,

Andreas Richter
