Davos (GR)
Site description
The Davos site (CH-Dav) is one of two forest sites within the Swiss FluxNet, a subalpine evergreen forest, located on the Seehorn mountain near Davos in the Swiss Alps. The site is dominated by Norway spruce, and is part of the external pageNABEL (Swiss air quality network)call_made and the external pagelong-term forest ecosystem research networkcall_made of the WSL. In addition, the site is the Swiss contribution within ICOS-CH to ICOS ERIC (Class 1 Ecosystem Station). Eddy covariance flux measurements are available since January 1997 (tower coordinates: 46°48'55.2" N and 9°51'21.3" E; WGS84 46.815333, 9.855917; at 1639 m asl).
