Please find below an additional referee report:

The article (amt-2017-399 : Intercomparison of aerosol measurements
performed with multi-wavelength Raman lidars, automatic lidars and
ceilometers in the frame of INTERACT-II campaign) is very good
scientifically and of interest to the community. I have only one concern.

There are problems with incorrect grammar that should be addressed
before publication. I list a few examples below, but one of the authors
needs to do a thorough check of the whole paper and re-write where necessary.

For example, the first two sentences of the introduction need a re-write.
Suggestions:

1. The monitoring of Essential Climate Variables (ECVs) using low-cost
and low-maintenance automatic systems represents a challenge for the
scientific community and instrument manufacturers over the next decade.

2. Automatic lidars do not report progress. They can report a signal.
Perhaps authors mean something like: The use of automatic lidars for
the vertical profiling of aerosol properties both in the boundary layer
and in the free troposphere has progressed steadily over the last few years.

There are also errors in the paper:

L18 "The campaign HELD"
L 60 "monitoring OF atmospheric aerosol"
L62 "Typically, THE higher..., THE higher..."

Perhaps it is too late to pass on these comments, but if not, I hope
they help.
