About FLUXNET

FLUXNET's data page explains how FLUXNET data is collected, processed, and made available for download. Eddy covariance methods at tower sites measure fluxes of scalars such as CO2, CH4, and water vapor, along with energy fluxes between the biosphere and the atmosphere. Local tower teams calculate and quality-control half-hourly or hourly fluxes. Regional networks and FLUXNET teams then standardize formats, run uniform quality checks, and produce gap-filled and flux-partitioned products.

The FLUXNET Shuttle provides access to continually updated, standardized data across multiple regional hubs, and is available as an open-source software library and a web interface. Earlier FLUXNET2015 and La Thuile datasets are static releases. The page links to data availability, data policies, variable explanations, processing pipeline details, change logs, and known issues, but the policy terms themselves are not summarized on this page.

FLUXNET FAQ

What does the FLUXNET Shuttle do?
The Shuttle provides a common way to discover and access standardized FLUXNET data across multiple regional hubs. It is available as an open-source software library and through a web-based graphical user interface.
What variables are measured at FLUXNET tower sites?
Eddy covariance methods quantify fluxes of scalars such as CO2, CH4, and water vapor, and energy fluxes such as sensible and latent heat. Continuous ancillary measurements include air temperature, precipitation, and radiation.
Where can I download FLUXNET data?
The page links to a Download Data section covering FLUXNET2015 and Community Products. Standardized data can also be accessed through the FLUXNET Shuttle.
