This research has been supported by the Prince Albert II of Monaco Foundation: 2487, Acknowledgements. The development presented in this paper was largely inspired by the initial PhD work of Janek Landsberg, which we gratefully acknowledge here. The research leading to these results has received funding from the Prince Albert II of Monaco Foundation “ANTARCTIC-SNOW” program, the ANR “EAIIST” project and the ADELISE “CNRS-LEFE” program. The deployment of this instrument in the field was made possible by the logistic support from the “NIVO2” and ADELISE “IPEV” programs. We thank the two reviewers for their useful comments which greatly improved the article.

International audience Obtaining precise continuous measurements of water vapor isotopic composition in dry places (polar or high-altitude regions) is an important challenge. The current limitation is the strong influence of humidity on the measured water isotopic composition by laser spectroscopy i...
