Welcome to ICOS Carbon Portal

TRANSCOM/IG3IS meeting, Lund 17-20 September 2018

What is ICOS?

ICOS is a pan-European research infrastructure for quantifying and understanding the greenhouse gas balance of Europe and its neighbouring regions. ICOS has received the official ERIC status 20 November 2015 (more on this in our NEWS section). ICOS now has 12 member countries and involves more than 120 measurement locations where greenhouse gas concentrations and fluxes are measured. ICOS provides long term and high quality observations, and plans to expand to many more countries and stations in the near future.

About the Carbon Portal

ICOS Carbon Portal is part of ICOS ERIC and offers access to research data, as well as easily accessible and understandable science and education products. All measurement data available in the Carbon Portal is quality controlled through the ICOS thematic centers:  Ecosystem, Atmospheric and Ocean Thematic Centers and a Central Analytical laboratory. Dedicated researchers all over the world will contribute to the elaborated products catalogue. The ICOS Carbon Portal is hosted by the University of Lund (Sweden) and Wageningen University (Netherlands) and is located in Lund, Sweden.

CO2 for a short period in summer 2017 from stations Zeppelin, Hyytiälä and OPE.

On 24 August 2018 ICOS ATC released an update of the Level 2 ICOS data for atmospheric stations! Level 2 data is final and fully quality controlled observational data. The new dataset contains data over 2016 to 2018 from all 11 atmosphere stations labelled in November 2017 and provides hourly averaged mole fractions of CO2, CH4 and CO, meteorological observations and two weekly integrated samples of 14CO2

The data can be browsed and downloaded from the Carbon Portal app by using this pre-configured search link. You can also download the complete dataset from the collection landing page .

All downloads require that you accept the ICOS data licence. When you use the data you should cite the data as follows:
