Data products

On this page
This page summarises the major data products offered by ICOS. These datasets are offered as collections of data and are released under the ICOS CC4BY licence. After the upcoming data releases in 2020 this page will also list ICOS level 1 and NRT data products from the ecosystem and ocean domains. All individual data objects offered by ICOS can be browsed through the main ICOS Carbon Portal data app.

ICOS Near Real Time Observational Data (Level 1)

Near Real-Time growing time series containing data from the atmospheric network of ICOS Research Infrastructure for the stations Gartow, Hohenpeißenberg, Hyltemossa, Ispra, Jungfraujoch, Křešín u Pacova, Lindenberg, Monte Cimone, Norunda, OPE, Pallas, Puy de Dome, SMEAR II (Hyytiälä), Svartberget, Torfhaus, Trainou, and Zeppelin Observatory.

ICOS Final Fully Quality Controlled Observational Data (Level 2)

This is the 2022-1 release of the ICOS final quality data product for eddy covariance fluxes and meteorological observations at 38 labelled ICOS stations in the ecosystem domain. The archives contain more detailed description of the different data files contained in the archives.

This 2022-1 release containing data from the atmospheric network of ICOS Research Infrastructure for 36 stations and 90 vertical levels at Birkenes, Gartow, Helgoland, Hohenpeißenberg, Hyltemossa, Ispra, Jungfraujoch, Jülich, Karlsruhe, Křešín u Pacova, La Réunion, Lampedusa, Lindenberg, Lutjewad, Monte Cimone, Norunda, OPE, Ochsenkopf, Pallas, Plateau Rosa, Puijo, Puy de Dôme, La Réunion, Ridge Hill, Saclay, SMEAR-II Hyytiälä, Station Nord, Schauinsland, Steinkimmen, Svartberget, Torfhaus, Trainou, Utö - Baltic Sea, Westerland, Weybourne and Zeppelin Observatory.

This is release 2021-1 of the final quality controlled Level 2 data from the ICOS Ocean network covering the period June-December 2021. This collection of 72 files was produced by labelled ICOS stations and processed following the ICOS Ocean data protocols using the QUINCE software tool (https://otc.icos-cp.eu/data-processing).

Historic Observational Time Series For ICOS and Non-ICOS Stations

 This is the release of the observational data product for eddy covariance fluxes at 73 stations in the ecosystem domain, part of them outside the ICOS network, covering the period 1989-2020. The data are in the standard format used for the ICOS L2 ecosystem products and also used by other regional networks like AmeriFlux.

This dataset for historic ambient N2O mole fractions is an important outcome of the FP7 InGOS project (http://www.ingos-infrastructure.eu, Grant Agreement Number 284274). Data from 12 stations have been reprocessed for the period 2000-2015; in some cases involving re-integration of chromatograms and in all cases re-calibrating the time series using updated assigned values for standard gases and target gases. All data have been brought to the same concentration scale (NOAA-2006A).

This dataset for historic ambient CH4 mole fractions is an important outcome of the FP7 InGOS project (http://www.ingos-infrastructure.eu, Grant Agreement Number 284274). Data from 17 stations have been reprocessed for the period 2000-2015; in some cases involving re-integration of chromatograms and in all cases re-calibrating the time series using updated assigned values for standard gases and target gases. All data have been brought to the same concentration scale (NOAA-2006A).

This is the release of the observational data product for eddy covariance fluxes at 52 stations in the ecosystem domain, part of them outside the ICOS network, from the Drought-2018 team and covering the period 1989-2018. The data are in the standard format used for the ICOS L2 ecosystem products and also used by other regional networks like AmeriFlux.

Atmospheric Greenhouse Gas Mole Fractions of CO2 collected by the Drought-2018 team, covering the period 1972-2018. Final quality controlled Level 2 data. During the most recent period, a selected set of stations, after being labelled as ICOS stations, follow the ICOS Atmospheric Station specification V1.3. Measurements and data processing for all time series is described in the paper below.

Elaborated Data Products (Level 3)

VPRM biosphere model results in Europe for 2006-2020. Biosphere-atmosphere exchange flux simulations were performed using: - Vegetation Photosynthesis and Respiration Model VPRM (Mahadevan et al., 2008, https://doi.org/10.1029/2006GB002735) - VPRM parameters optimized for the year 2007 using 46 sites within Europe (available from www.europe-fluxdata.eu) - VPRM preprocessor code version Rev.116 - VPRM optimization code version Rev.7 - VPRM offline code version Rev.
