ETH - Grassland Sciences

Managed (grazed) alpine grassland at 1900-2500 m asl, mainly on calcareous bedrock. The area and the adjacent facilities are part of the ETH Research Station. Eddy covariance flux measurements were carried out in campaign mode during summer in 2006 to 2008 (tower coordinates: 46°34'59.5" N and 9°47'25.5" E at 1978 m asl).
