Alp Weissenstein / Crap Alv (GR)
Site description
Alp Weissenstein (CH-Aws) is one of the three grasslands within the Swiss FluxNet, but the only one with two names: Crap Alv, as it is called in the local language Romansh.
It is a managed (grazed) alpine grassland at 1900–2500 m asl, mainly on calcareous bedrock. The area and the adjacent facilities are part of the external pageAgro-Vet Strickhof. For the long-term history of the site, see external pagehere. Eddy covariance flux measurements were carried out in campaign mode during summer in 2006 to 2014 (tower coordinates: 46°34'59.5" N and 9°47'25.5" E; WGS84 46.583194, 9.790417; at 1978 m asl). Since 2014, measurements are running continuously.
