ED: Publish subject to technical corrections (22 Feb 2021) by Farahnaz Khosrawi

Dear authors,

I am pleased to inform you that your paper is accepted for publication after consideration of the technical corrections given below.

Best regards, Farahnaz Khosrawi

Technical corrections:
------------------------------
P1, L3 and L4: The acronyms of the campaigns are used without introducing them. Please add what these are standing for.

P2, L45: Same here

P3, L2: due sedimenting -> due to sedimenting

P4, L120: Van dop etal., -> Van Dop et al. (?)

P5, L155: The acronym ECMWF has not been introduced.

P6, L181: Also WARAN has not been introduced.

P6, L182:lyman-alpha -> Lyman-alpha

P7, L194: Also here the acronyms have not been introduced.

P7, L197: averaging -> average

P8, L218: Figueras i Ventura et al. (2020) ???

P8, L221: The acronym PETRAS has not been introduced.

P17, L417: the flight on 500 hPa at 14:50 UTC -> the flight at 500 hPa at 14:50 UTC

P18, L441: It is weird to say "if the model is assumed". Either the model does underestimate precipitation or it does it not. This should be known. If you would like to express this more carefully you could write that the negative bias indicates an underestimation of precipitation by the model.

P19, L455: by Falcon -> by the Falcon

P19, L457: ascends less......-> than what?

P20, Fig 7 caption: 2-pvu -> 2-PVU

P23, L516: release tracer -> release a tracer

P24, L534: way -> path

P24, L540: peaks in tracer probabilities -> peaks in the tracer probabilities

P24, L549: Something is wrong/missing in this sentence.

P24, L550: "probability in Fig. 5" is not a good wording. It should read as "seen" or "shown" in Fig. 5

P24, L551: with the WCB -> within the WCB (?)

P28, L627: This is not clear. These are the first measurements, but similar measurements have been made two years later and your study is going to be published several years later. So even if these are the first measurements this is not necessarily the first study. So what is the point with mentioning this?

Short summary

Warm conveyor belts (WCBs) are important airstreams in extratropical cyclones, often leading to the formation of intense precipitation. We present a case study that involves aircraft, lidar and radar observations of water and clouds in a WCB ascending from western Europe across the Alps towards the Baltic Sea during the field campaigns HyMeX and T-NAWDEX-Falcon in October 2012. A probabilistic trajectory measure and an airborne tracer experiment were used to confirm the long pathway of the WCB.
