In the begining of May 2021 we installed an Eddy Covariance station in the urban forest of Lange Erlen. The station is equipped with an IRGASON (Integrated CO2 and H2O Open-Path Gas Analyzer and 3-D Sonic Anemometer), mounted at the top of a pneumatic mast, reaching 30 m above ground. The forest canopy surrounding the station has an average height of 16 m. The station is also equipped with soil sensors for the measurement of soil temperature and soil water content, while in the surrounding area we have installed soil collars for soil respiration measurements with a portable gas analyser.

The station will remain active for at least the summer of 2021 and the data collected will be used for the direct evaluation of the biogenic CO2 flux model of diFUME. Together with the permanent station located at a grassland nearby (BLER), we will have enough data to evaluate the model performance of the biogenic components at different ecosystem types.

The data will be constantly uploaded in the mcr database and can be reached through our online interface.
