Isotope values of fresh snow samples and daily temperature from Neumayer station in the period 1981-2000 ...
The relationship between d18O and air temperature at Neumayer station, Ekströmisen, Antarctica, was investigated using fresh-snow samples from the time period 1981-2000. A trajectory model that calculated 5 day-backward trajectories was used to study the influence of different synoptic weather situa...
