GREENHOUSE GASES MONITORING AT AMSTERDAM ISLAND

The goal of
the greenhouse gases measurement program at Amsterdam Island is to contribute
to long term atmospheric monitoring within the framework of the ICOS-France
National Observation Service and the international GAW (Global Atmospheric
Watch) network from World Meteorological Organization. Amsterdam Island is a
reference site for atmospheric watch (clean site), and measurements conducted in-situ
enable us to better estimate the austral ocean impact as a carbon sink and
better understand the associated mechanisms. This location is also well suited
to trace emission transport coming from South Africa. In addition to continuous CO2 and CH4
measurements and weekly flask sampling (CO, H2, N2O, CO2 isotopes)
conducted since several years, we propose to set up continuous CO and N2O
measurements and to restart the O3
monitoring over the next 4 years. The 222-Radon measurements as well as
meteorological parameters which enable an accurate air masse origin characterization
will be continued. In order to further increase our knowledge about the Austral
Ocean carbon sink, we think about setting up a continuous and high precision atmospheric oxygen analyzer.
