Water vapor observation in the lower atmospheric boundary layer at Dome C, East Antarctic plateau Christophe Genthon, Dana Veron, Etienne Vignon, Jean-Baptiste Madeleine, Luc Piard https://doi.org/10.1594/PANGAEA.939425

Short summary

The surface atmosphere of the high Antarctic Plateau is very cold and clean. Such conditions favor water vapor supersaturation. A 3-year quasi-continuous series of atmospheric moisture in a ~40 m atmospheric layer at Dome C is reported that documents time variability, vertical profiles and occurrences of supersaturation. Supersaturation with respect to ice is frequently observed throughout the column, with relative humidities occasionally reaching values near liquid water saturation.
