Short summary
Natural atmospheric supersaturation is a norm rather than an exception at the surface of Dome C on the Antarctic Plateau. This is reported by hygrometers adapted to perform in extreme cold environments and avoid release of excess moisture before it is measured. One year of observation shows that atmospheric models with cold microphysics parameterizations designed for high altitude cirrus reproduce frequently but fail with the detailed statistics of supersaturation at the surface of Dome C.
