A Motion-Correction Method for Turbulence Estimates from Floating Lidars

Round 1

Reviewer 1 Report

The paper presents a method to correct/compensate turbulence intensity (TI) overestimations from floating lidars (FLS) because of their buoy motions.

Section 1 is well written and introduces the reader to the floating lidars measurement particularities, providing a sufficiently complete selection of references and previous works in this field.

Section 2 describes the proposed methodology starting from the principle of lidar VAD configuration, followed by the introduced ‘turbulence box’ concept and the simulations of buoys motions.

Results in Section 4 show that the proposed ‘turbulence box’ method seems to be able to reproduce the differences found onshore between fixed lidars and cups/sonics mounted on met masts (Figure 5 and especially Figure 9). Therefore, the background principle of the motion correction/compensation is well founded. The weak point of the results is that their correction scheme seems to fail at the highest height, but authors provide sufficient reasoning and possible improvements.

Overall, my opinion is that the paper is well written and merits publication.

Reviewer 3 Report

[1] Line 23: Suggest to change “profiling wind lidars” to “wind profiling lidars”.

[2] Line 29: Suggest to change “bankable” to “profitable”.

[3] Line 76: Please elaborate “atmospheric turbulence boxes”.

[4] Figure 1, caption: Suggest to change “VAD typical” to “typical VAD”.

[5] Eqn.(9): The subscript “i” is confused with imaginary unit “i”.  What is “1” in the exponent?

[6] Eqn.(11): Please define “u’_i”.

[7] Line 141: Please list the expression of “\Phi_{ij}” in Mann model.

[8] Eqns.(15), (16), (17): The subscript “i” is confused with imaginary unit “i”.  What is “1” in the exponent?

[9] Line 169: Why choose L_x much larger than L_y and L_z ?

[10] Line 171: Please elaborate “velocity vertical shear” and how it is related to this work.

[11] Figure 4: Please specify the color bar.

[12] Line 336: Please define “focused heights”.
