The manuscript has improved a lot since the first submission.
There are still three points to consider:
1.) A HWP used to calibrate or to correct for alpha works only, if the depolarization measurement is performed at a single wavelength. A HWP for 532 would be a quarter wave plate for 1064 and introduce circular (or elliptical) polarization. Dual-wavelength polarization lidars need a HWP for each wavelength to perform a calibration.
2.) The change from 0 (zero) to O like Optics has been done everythere except of Equation (17). Please change it.
3.) p16, l26-27 You mix particle and volume linear depolarization ratio. The first part of the sentence describes the particle linear depolarization ratio (which is around 0.22, see Fig. 9), whereas the second part of the sentence describes the volume depolarization ratio, which is close to the molecular depolarization ratio. |
