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.

Due to the maintenance of the FFNet Database, we are not accepting any data requests. We are sorry for the inconvenience.
