Suggestions for revision or reasons for rejection

I am happy with most of the responses to my comments and i am pleased to see that the authors have computed the splinter production rates.

The authors then go on to use the computations to indicate that they should not include these results in the paper. Here i disagree and think that including these results would be useful for the community for two reasons.

i) If the analysis suggests that it is not possible to estimate splinter rate from aircraft measurements with current technology, then this is a result that it would be good to share.

ii) Using their approach the authors could generate a diagram that shows the ratio of predicted to measured splinters as a function of fraction of particles assumed to be columns and the fraction assumed to be graupel?
The authors could talk about what would be required for the data to be in agreement with the laboratory results and whether there are techniques that could be used to constrain that fraction.

In addition, here are some thoughts related to the current analysis:

Is there a need to worry about column fraction, given that the contribution to number concentration from primary nucleation is thought to be insignificant? The ratio of predicted to measured splinter production rate would be dependent upon graupel fraction only.

From fig. R6 it looks like the graupel fraction would need to be ~0.1 of the >800 micron sized particles for the centroids of each case's data is on the 1:1 line? It might be possible to do an assessment using human particle shape interpretation on some representative imagery to estimate if the graupel fraction is 1 in 10 of the particles larger than 800 microns?

Therefore, i would like to see the inclusion of a discussion that outlines the findings and limitations of their splinter rate analysis.
