Macrocosms

The Macrocosms platform is the largest of the 3 platforms of the European Ecotron in Montpellier. It is made up of 12 identical and independent experimental units dedicated to research on ecosystems and biological communities.

(volume of ~40m³) in which  atmospheric conditions are controlled. Designed to operate in natural light, the platform can also operate in controlled light conditions.
Under each dome, a belowground chamber hosts a large instrumented lysimeter (2 to 12 tonnes, soil depth up to 2 m, canopy area 2, 4 or 5 m², canopy height up to 2 m), and the machinery for the environmental controls.

The facility is unique for permitting accurate simulations of wide range of environmental scenarios as well as the measurement of evapotranspiration flows, while simultaneously providing measurements of flows of major greenhouse gases (CO2, CH4 and N2O) at the ecosystem scale. The gas measuring system remains flexible and offers the possibility to carry out additional measurements.
