Last update: 11 Aug 2021
The table below shows currently available flux products.
Most of the fluxes are currently shared via the FLUXNET database. Recently shared data might not yet be available for download due to additional data processing applied by the database (e.g., u* filtering, gap-filling, partitioning). See here for details about flux levels and data shared with FLUXNET.
Fluxes are shared with FLUXNET via the European Fluxes Database Cluster (EFDC).
See end of page for Legend and Changelog.
