  • Benetti, M.; Lacour, Jean-Lionel; Sveinbjörnsdóttir, Árný; Aloisi, G.; Reverdin, G.; Risi, C.; Peters, A. J.; Steen‐Larsen, H. C. (American Geophysical Union (AGU), 2018-03-10)
    We propose a framework using water vapor isotopes to study mixing processes in the marine boundary layer (MBL) during quiescent conditions, where we expect evaporation to contribute to the moisture budget. This framework complements the existing models, ...
  • Benetti, Marion; Reverdin, Gilles; Holliday, Penny; Olafsdottir, Solveig; Lherminier, Pascale; Sarthou, Geraldine; De Steu, Laura; Sveinbjörnsdóttir, Árný; Valdes, Sinhue Torres; Tynan, Eithne; Yashayaev, Igor; Olafsson, Jon (European Geosciences Union, 2017)
    We investigate whether one can detect changes in the freshwater contributions to the North Atlantic subpolar gyre(SPG), in light of the observed recent decrease of salinity in the region. We focus on two important conduits offreshwater from the ...
  • Lacour, Jean-Lionel; Flamant, Cyrille; Risi, Camille; Clerbaux, Cathy; Coheur, Pierre-François (Copernicus GmbH, 2017-08-10)
    The isotopic composition of water vapour in the North Atlantic free troposphere is investigated with Infrared Atmospheric Sounding Interferometer (IASI) measurements of the D ∕ H ratio (δD) above the ocean. We show that in the vicinity of West Africa, ...
  • Steen-Larsen, H. C.; Sveinbjörnsdóttir, Árný; Jonsson, Th.; Ritter, F.; Bonne, J.-L.; Masson-Delmotte, V.; Sodemann, H.; Blunier, T.; Dahl-Jensen, D.; Vinther, B. M. (American Geophysical Union (AGU), 2015-06-24)
    The isotopic composition of near surface (or planetary boundary layer) water vapor on the south coast of Iceland (63.83°N, 21.47°W) has been monitored in situ between November 2011 and April 2013. The calibrated data set documents seasonal variations ...

    Water isotopes are powerful tracers of the hydrological cycle and can be used to serve many purposes in climateresearch. Here, we use water isotopic measurements – in the vapour and in the precipitations – from Bermudaand Iceland measurement facilities, ...
  • Stevens, Bjorn; Brogniez, Hélène; Kiemle, Christoph; Lacour, Jean-Lionel; Crevoisier, Cyril; Kiliani, Johannes (Springer Science and Business Media LLC, 2017-07-26)
    In situ, airborne and satellite measurements are used to characterize the structure of water vapor in the lower tropical troposphere—below the height, z∗, of the triple-point isotherm, T∗. The measurements are evaluated in light of understanding of how ...
