Suggestions for revision or reasons for rejection

First of all, there have been a number of improvements to the paper with regards to the adding of additional details which significantly helped to improve the paper. But, it also left a number of inconsistencies that need to be removed before publication. First, as I read into the details, I saw in lines 182 through 184 that only one case was used to train the convective portion of the SVM technique… This seems very small.... If this is true, how many cases (not just radar tilts) were used to train the stratiform portion of the SVM technique... This is one of the chief reasons I rated the scientific quality as only fair.... Otherwise, I would've rated it higher.

Also, the overall readability and the English needs to be improved significantly.... The reason is there are statements written that will convey to the reader an opposite meaning than what the authors clearly intended. An example, can be found in line 227.... Where the authors mention that POD, FAR and CSI can't really capture the performance of the SVM technique… If that were true why bother with those statistics… However, I think the authors really meant that these statistics only partially capture the performance and therefore a new performance evaluation statistic should also be considered. The same subject was also mentioned in the conclusion in lines 332 through 335 and should be clarified there as well.....where it significantly caused me to wonder why the stats were even used..... Again, I know the authors didn't intend that meaning..... But the way it is written conveyed that type of meaning.

While I think the authors significantly improved the amount of detail needed for publication and that there is significant scientific merit to the work I just don't think it's ready for publication yet without significant major revisions to improve the readability of the paper. However, I definitely think this paper should be revised because I believe it does carry information that would be useful for the scientific community once the revisions are made. While I know this may be discouraging for the authors, they need to realize that important that they keep moving forward on this paper because persistence will ultimately result in excellence!

Short summary

The motivation of this work is to develop a precipitation separation approach that can be implemented on those radars with fast scanning schemes. In these schemes, the higher tilt radar data are not available, which poses a challenge for the traditional approaches. This approach uses artificial intelligence, which integrates polarimetric radar variables. The quantitative precipitation estimation will benefit from the output of this algorithm.
