Description

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). Data have been flagged for identified periods with instrumental or sampling problems. Next to added estimations for measurement uncertainty based on repeatability of the working standards also error estimates are added that represent uncertainty due to lab internal scale consistency, monthly reproducibility, scale transfer and where available comparison with concurrent flask sampling.

Drought-2018 ecosystem eddy covariance flux product for 52 stations in FLUXNET-Archive format

Citation
Drought 2018 Team and ICOS Ecosystem Thematic Centre: Drought-2018 ecosystem eddy covariance flux product for 52 stations in FLUXNET-Archive format, , doi:10.18160/YVR0-4898, 2020.
Description

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. The processing has been done using the ONEFlux processing pipeline (https://github.com/icos-etc/ONEFlux) and is fully compliant and integrable with the FLUXNET2015 release (https://fluxnet.fluxdata.org/) and other datasets processed with the same pipeline (AmeriFlux, ICOS L2)

ICOS Near Real-Time (Level 1) Atmospheric Greenhouse Gas Mole Fractions of CO2, CO and CH4, growing time series starting from latest Level 2 release

Disclaimer

Near Real-Time (NRT, Level 1) data is not the final highest quality ICOS data. This data is generated using only completely automated quality control procedures. These NRT time series are generated within 24 hours after measurement and will not be updated later using improved information or become completed with missing data. For your analysis and publications we recommend to use the final completely quality controlled and flagged (Level 2) data that is released with a delay between 6-12 months, that includes all corrections and maximum completion of missing data, also listed in our data products catalog.

Description

Near Real-Time growing time series containing data from the atmospheric network of ICOS Research Infrastructure for the stations shown below in the tables. This collection contains the NRT hourly averaged data for the mole fractions of CO2, CO and CH4, measured at the relevant vertical levels of the measurements stations, starting from the latest date of final released Level 2 data or the date of labelling. All stations follow the ICOS Atmospheric Station specification V2.0 (https://doi.org/10.18160/GK28-2188) and are certified as ICOS atmospheric stations Class I or II. Data processing has been performed as described in Hazan et al., 2016 (https://doi.org/10.5194/amt-9-4719-2016).
