FFPRI FluxNet Database (FFNet DB)

The FFPRI FluxNet offers a micro-meteorological database obtained in our observation network. The database contains the observed flux data of energy, water vapor and carbon dioxide between the forest and the atomosphere. It also takes in the micro-meteorological elements such as air temperature, air humidity, wind velocity and solar radiation above the forest canopy.

To use the data in the FFPRI FluxNet database, users must consent to the Fair Use Policy.
The online application to download data is available from the Data Request page.
