Site Description
This site was part of the CarboEuropeIP project (EU FP6) and the GHG-Europe project (EU FP7). Eddy covariance flux measurements started in December 2003. The soil type is an eutri-stagnic cambisol. The site is located at 452 m and is managed as a typical intensive crop rotation under the Swiss Integrated Pest Management regime (IP Suisse). The tower coordinates are: 47°17’11.1″ N and 7°44’01.5″ E; WGS84 47.286417, 7.73375. During the CarboEuropeIP project, colleagues from Agroscope operated the Oensingen Grassland site nearby.
