| Zusammenfassung |
| We report results from our atmospheric flask sampling network for three
European sites: Lutjewad in the Netherlands, Mace Head in Ireland and the
North Sea F3 platform. The air samples from these stations are analyzed for
their CO2 and O2 concentrations. In this paper we present the
CO2 and O2 data series from these sites between 1998 and 2009, as
well as the atmospheric potential oxygen (APO). The seasonal pattern and
long term trends agree to a large extent between our three measurement
locations. We however find a changing gradient between Mace Head and
Lutjewad, both for CO2 and O2. To explain the potential
contribution of fossil fuel emissions to this changing gradient we use an
atmospheric transport model in combination with CO2 emission data and
information on the fossil fuel mix per region. Using the APO trend from Mace
Head we obtain an estimate for the global oceanic CO2 uptake of 1.8 ±
0.8 PgC/year. |
