Forest and land-surface Carbon and Water Exchange

3

Von 10/2014 bis 12/2020

Schwerpunktleiter: Christoph Thomas
Mitarbeiter: Christoph Thomas, Wolfgang Babel, Johannes Olesch, Kanisios Mukwashi

We conduct observations of forest carbon and water exchange using the eddy covariance technique at various sites across the globe including the long-term measurements at the Waldstein-site in the Fichtelgebirge Mountains, Bavaria. Please visit the current weather stations data to access the most recent observations.
