Facilitating Access to Global Observing Systems Data and Information

FLUXNET Data Access

Data Availability: Data are available online in various formats on the main FLUXNET site, the Oak Ridge National Laboratory (ORNL), (FLUXNET data) and on the following regions web sites: North and South America (AmeriFlux), Europe (CarboEurope), Asia (AsiaFlux), Australia and New Zealand (OzFlux), and Korea and Thailand (KoFLux). Additionally, 3-year 13-site European data are available on the EUROFLUX project web site.

The role of FLUXNET is to integrate worldwide CO2 flux measurements by providing monthly and annual heat, water vapor, CO2, ecological site data and gap-filled flux and remote sensing products for over 150 global sites.

Access the Databases

In general, data and information generated or supplied through FLUXNET will be readily available online in a free and unrestricted manner within 2 years after the date of collection.

  • Data Policy: Kindly inform the appropriate Principal Investigators of how you are using flux and site data and of any publication plans. If the Principal Investigators feel that they should be acknowledged or offered participation as authors, they will let you know, and we assume that an agreement on such matters will be reached prior to publishing and/or use of the data for publication. If your work directly competes with the Principal Investigator's analysis, he or she may ask that they have the opportunity to submit a manuscript before you submit the one that uses their data. In addition, when publishing a paper using flux data, please acknowledge the agency that supported the flux tower research. (More information)

Checked and verified data will be placed in the public domain and made readily accessible through the following sites:

  • Global flux data sets (FLUXNET) containing net biosphere-atmosphere CO2 exchange (NEE) data, gap-filled flux data, site specific meta data and information, long term climate data, and artic tundra data. Data are available for download.

| Access FLUXNET data sets |

  • Gap-filled flux products and meteorological data for half-hourly, daily, weekly, monthly, and annual time intervals are presented for each site and year. Also knows as the Marconi Data Sets and will retain these data sets as an individual unit, although the data were updated and expanded in 2002. Users are urged to communicate with the contributing investigators and are reminded that data, when used for publication, are subject to change.

| Access the Gap-filled flux data and data sets |

  • North and South America (AmeriFlux). Data are available for download.

| Access the AmeriFlux data |

  • Carbon balance of Europe (CarboEurope). Data are available upon request.

| Access the CarboEurope data |

  • Japan, China, Thailand, Indonesia, Siberia, Alaska, Artic (AsiaFlux). Only tower information is available by request.

| Access the AsiaFlux data |

  • Korea (KoFlux). Only tower information is available.

| Access the KoFLux data |

  • Australia and New Zealand (OzFlux). Tower information and data are available.

Data is currently unavailable online.
  • 3-year flux data of CO2, water vapor, and energy exchange for 15 forest sites representative of the European basin (EUROFLUX) are available.

| Access EUROFLUX data |

  • Fluxnet-Canada A national research network bringing together university and government scientists to study the influence of climate and disturbance on carbon cycling along an east-west transect of Canadian forest and peat land ecosystems. Data available by request.

| Access Fluxnet-Canada data |

 

Other Data

  • FLUXNET Long-term climate data.   Long-term means and variances that will provide the baseline for evaluating meteorology records for specific years as recorded at the flux tower and will also provide information for climate modelers to initialize and verify their models.

| Access FLUXNET long-term climate data |

  • Arctic Tundra Flux Study. 1994 to 1996 data available on ftp server.

| Access Arctic Tundra Flux Study data |

  • Net Carbon Flux Data

| Access Net Carbon Flux data |

  • The FLUXNET Web Map Server allows users to select from more than 210 sites in the FLUXNET Global Network and to retrieve information about site characteristics as well as retrieve flux data, if available.

| Access the FLUXNET Web Map Server |

  • The goal of the MODIS ASCII Subset activity is to prepare summaries of selected MODIS Land Products for the community to use for validation in conjunction with FLUXNET and other field data. These summaries include pixel values of selected land products for a 7-km x 7-km area around the flux towers or field sites. The data are available from the ORNL DACC's FTP site.

| Access the MODIS ASCII Subset Data |

  • The MODIS Web Map Server is a map server for MODIS subsets and allows users to choose from more than 270 sites worldwide and retrieve files for selected MODIS Land Products in tower and field sites.
