The manuscript presents the data collected during the EURAC4A-iso measurements, a sub-part of the EURA4C field campaign dedicated to isotopic measurements.

I find this manuscript very well written, with clear depictions of the various isotopic measurements. I do not have strong concerns about this manuscript, and believe that this manuscript could be published after the really minor comments below have been taken into consideration.

Remark : the unit “nmi” is used for distance, but is non-SI. A SI unit should be used.

Line 85-90 : I do not understand how isotope ratios can help differentiate boundary layer air and free tropospheric air. It seems to be a shortcut, but this shortcut is not straightforward. Please explain.

Lines 660-665 : Does this part refers to Figures 9 and 10 ? The titles of these 2 figures (9 and 10) only states “campaign-mean (…)”. The 3 vessels (Atalante, Meteor and Brown) didn’t have the same legs, so I wonder how campaign-means can be reasonably used to look at the consistency between the measurements : there are differences in the length of the measurement period, and there are differences in the areas that have been sampled. Can you comment ?

Figure 13: the unit of dD is missing.

Short summary

One of the novel ways EUREC⁴A set out to investigate trade wind clouds and their coupling to the large-scale circulation was through an extensive network of isotopic measurements in water vapor, precipitation, and seawater. Samples were taken from the island of Barbados, from aboard two aircraft, and from aboard four ships. This paper describes the full collection of EUREC4A isotopic in situ data and guides readers to complementary remotely sensed water vapor isotope ratios.
