#ICOScapes | Jungfraujoch (Switzerland) | Greenhouse gas observations


Jungfraujoch is the highest station in the
ICOS network. In contrast to most of the ICOS stations that
equip with tall towers on rather flat terrain we are here in a very complex terrain in the Swiss alps and we’re sitting on a kind of a natural tall tower
at 3500 metres above sea level. Access to the research station is very convenient we can access it with a train. It’s the highest railway station in Europe. Since we are in the free troposphere, time
series are usually very smooth and provide background information
which is very key information for comparison with measurements
at more polluted sites. Since the difference between the background
that you can measure here and the polluted sites at further down, it’s a very good proxy for emission estimates of greenhouse gases. Sometimes, also Jungfraujoch is exposed to the
boundary layer air masses from further below. And due to the mixing, during transport, you get a nice integrated signal
of sources and sinks of a large area. And like that, we can, with one single station to see sources and sinks from
large area in Central Europe. I feel really privilege to work up here. It’s such a beautiful and unique place which is also a part of the
UNESCO World Natural Heritage. The climate change is visible here, for example,
when I look the glacier just down here The Aletsch Glacier, the longest glacier in Europe. At the thickest place there
is around 900 metres of thickness but it is still loses about 0.6 metres
per year on thickness. I really feel that our long-term records here become more and more
valuable the longer they get. Every day we add more data to that. And in the future, if we can continue
doing these measurements they will be even more valuable.
