Group picture of Brazilian, American and German scientists in front of setting sun. You can see only the silhouette of 5 people who put their arms on and around each other's shoulders, in front of a magical sunset. The sky shows a color gradient from purple-blue to golden-orange.

Tanguro (Brazil)

Cooperation with the Institute for Amazon Research (INPA)

Investigation of three different sites in the Amazon for carbon utilization.

Description & History

In November 2013, two new Eddy-Flux sites were established in Ribeirão Tanguro, Matto Grosso, Brazil. One of them in a burned forest area, the other in an unmanaged and undisturbed forest that serves as a comparison area. A third tower was erected in February 2015 in an area of intensive agriculture (soy) located near these forests.

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

The towers are part of a joint project with the Brazilian Institute for Amazon Research (INPA) with the question of whether the efficiency of carbon use of tropical forests can be changed.
