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 CO 2 and CH 4 measurements and weekly flask sampling (CO, H2, N 2 O, CO 2 isotopes) conducted since several years, we propose to set up continuous CO and N 2 O measurements and to restart the O 3 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.
