Domes with adjustable windows (established in 1997) represent a technological approach for in situ investigation of long-term impacts of elevated CO2 on juvenile trees/forests characterized by an intense community level and canopy closure phase. Lamellar windows are constructed from UV-transparent poly-acrylic material closing from the windward side to safe CO2 consumption. The windows can automatically close during the rainy days to investigate drought effect (multi-factorial experiments). Air-conditioning device ensures to keep an ambient temperature. Fumigation with elevated CO2 (700 ppm) is provided during the vegetation season (May-October).

Relevant Research Questions

Long-term multifactorial effects (elevated CO2, UV, drought, mineral nutrition supply etc.) on tree saplings grown in small (10 x 10 m) stand, i.e. including the mutual interactions among trees. Physiological processes, growth/morphology, changes in metabolic composition are investigated.


multifactorial experiments are available; complex measurement of environmental characteristics according ICOS protocols; electricity available; relatively low operation costs (low CO2 consumption); high elevation (ca 900 m a.s.l.)


The facility has one dome with ambient and one dome with elevated CO2 concentration are available; experiments during winter time are unavailable or very limited.

Experimental Capabilities

Experimental Facilities

Experimental roofs (shelters) enabling manipulation of an incoming precipitation, an intensity/spectrum of incident solar radiation, and an emissions of long-wave thermal radiation (manipulation of air temperature) and their mutual interactions.

Experiments duration: Months, Weeks, Years;

Experimental Aerea

Total area: 200 m²

100m2 ambient CO2 in total, 100 m2 elevated CO2 in total
