Here you can search for ICOS data. Below you can pre-select if you want to search for observational data from the ecosystem, atmosphere and ocean stations or elaborated products produced from ICOS or other data, before coming to the Data Portal. Selecting Advanced search will bring you directly to the Data Portal without pre-selection. After selecting data sets in the Portal you can preview the data. Put the data sets you like into a cart. From there, you can visualize again or download all or parts of the data set contents. A more detailed description of the data download process is given under getting started.
