Available Flux Products

The table below shows currently available flux products.

Fluxes are shared with FLUXNET via the European Fluxes Database Cluster (EFDC). See here for details about data shared with FLUXNET.

Major FLUXNET data collection initiatives:

• ICOS/FLUXNET: continuous (yearly) releases since 2024, data can be downloaded via the ICOS Carbon Portal
• ICOS/FLUXNET Warm Winter 2020 Initiative: collected 2021, contains data until 2020 (more info)
• FLUXNET European Drought Study 2018: collected 2019, contains data until 2018 (more info)
• original FLUXNET2015: collected 2016, contains data until 2014 (more info)
• FLUXNET-CH4-2020 Community Product V1: collected 2019, contains various years (more info)
• N2O initiative: details follow

Datasets

• Available current versions of FLUXNET and PI datasets
• Up to Level-4
• For info about the different flux levels, see Flux Processing Chain

Available Level-1 Fluxes

• For info about the different flux levels, see Flux Processing Chain
• Level-1 fluxes are final flux calculations and the basis for all further flux level.
• Level-1 fluxes are without extended quality flags (Level-2), storage correction (Level-3.1), outlier removal (Level-3.2), USTAR filtering (Level-3.3), gap-filling (Level-4.1) and NEE partitioning (Level-4.2).
• Tool for finding Level-1 fluxes: Flux Finder

Legend

• Current Version … Newest available flux version
• EFDC Calcs … Shows if the EFDC Version contains NEW data (data for the respective year was never uploaded before), or updated (UPDATE) data (another version of the data for this year was shared before).
• EFDC Upload … Most recent date when the Level-1 or Level-2 fluxes were uploaded to the EFDC for data sharing within FLUXNET.
• EFDC Version … Flux version available within the most recent FLUXNET dataset. This is the most recent flux version that was uploaded to EFDC. This version can be different from Current Version if the Current Version was calculated after the most recent FLUXNET / EFDC upload deadline.
• GA … Gas analyzer
• HS50 … Gill HS-50 sonic anemometer
• IRGA62 … LI-COR 6262 closed path infrared gas analyzer (CO₂, H₂O)
• IRGA72 … LI-COR 7200 enclosed path infrared gas analyzer (CO₂, H₂O)
• IRGA75 … LI-COR 7500 open path infrared gas analyzer (CO₂, H₂O)
• Level … Highest available flux level. For more info about flux levels see here: Flux Levels Refined
• LGR … Los Gatos analyzer (CH₄ / N₂O)
• QCL … Quantum cascade laser by Aerodyne (CH₄ / N₂O)
• SA … Sonic anemometer.
• Site & Year … year; note that in some years the setup of the instruments might have changed. In these cases results from different time periods are merged into one single file for the respective year. In this table, the parts are not listed, only info for the full year.
