Reactive gases in the Dome C snowpack, Antarctica, 2012--2014 D. Helmig https://doi.org/10.18739/A2FP03

Short summary

We present 15 months of trace gas observations from air withdrawn within the snowpack and from above the snow at Concordia Station in Antarctica. The data show occasional positive spikes, indicative of pollution from the station generator. The pollution signal can be seen in snowpack air shortly after it is observed above the snow surface, and lasting for up to several days, much longer than above the surface.
