  abstract = {{During the summer 2012, we carried out continuous measurements of the
isotopic composition ({$\delta$}) of water vapor over the near-surface
subtropical North Atlantic Ocean (STRASSE cruise). In this region of
excess evaporation, we investigate the control of evaporation and mixing
with a lower troposphere-derived, isotopically depleted air mass on the
near-surface {$\delta$}. We use a simple model to simulate the near-surface
{$\delta$} as the result of a two end-member mixing of the evaporative flux
with free tropospheric air. The evaporative flux {$\delta$} was estimated
by the Craig and Gordon equation while the {$\delta$} of the lower
troposphere was taken from the LMDZ-iso global atmospheric circulation
model. This simulation considers instantaneous mixing of lower
tropospheric air with the evaporated flux and neglects lateral
advection. Despite these simplifications, the simulations allow to
identify the controls on the near-surface {$\delta$}. The d-excess
variability is largely a consequence of varying kinetic effects during
evaporation, even during a convection event when the input of
tropospheric vapor was strong. Kinetic effects and mixing processes
affect simultaneously the near-surface {$\delta$} and result in the vapor
occupying distinct domains in the {$\delta$}$^{18}$O-{$\delta$}D space.
The relative humidity-d-excess relationship shows that the closure
assumption overestimates the d-excess variability at short time scales
(less than a day). We interpret this as due to an effect of the
residence time of the near-surface water vapor on the d-excess. Finally,
we highlight the importance of reproducing mixing processes in models
simulating isotopes over the subtropical North Atlantic Ocean and
propose an extension of the closure assumption for use in initial
conditions of distillation calculations.
