Description & History

In November 2013 three new Eddy flux stations were set up in Ribeirão Tanguro, Matto Grosso, Brazil. One in a burnt forest, one in an unmanaged forest (control site) and another one on a farmland (soy beans), next to these woods, was set in February 2015.

They are equipped with the usual sensors for meteorology and Eddy covariance measurements and are powered by solar stations.

The towers belong to a joint project with the Brazilian Institute for Amazon Research (IPAM) to manipulate the carbon use efficiency of tropical forest.
