Ten more ICOS stations certified for greenhouse gas measurements

After passing a rigorous quality assurance process, 10 new measurement stations have received the status of an ICOS labelled station. The newly certified stations are located in Finland, France, Germany, Italy, Netherlands and Spain. 

After the 10 new labels, altogether 124 out of the 173 ICOS stations have been standardised for greenhouse gas measurements. Station labelling is one of the key ways ICOS keeps the quality of its data high and ensures its usability in climate research. To receive the label of a standardised greenhouse gas measurement station, all ICOS stations have to pass a demanding standardisation and quality control programme. 

The station labelling is an intricate process for the final implementation of ICOS standards and a compliance check for the stations. Station labelling starts with a formal application that also needs approval by the national government. The station can apply for Class 1 station, Class 2 station, or in the case of ecosystem stations, an Associated station label.

Four decades of greenhouse gas data from the subtropics 

Among the newly labelled stations is the Izana observatory, whose data is a highly valuable addition to the ICOS network. The station is located on the island of Tenerife, Canary Islands, 300 kilometers from the African coast.

“We have a centenary experience, more than 100 years of collecting meteorological data and more than 40 years of collecting greenhouse data. For ICOS, we will take CO2 and CH4 measurements, which are mandatory measurements for an ICOS station. Additionally, we will take N2O and CO measurements,” says Pedro Pablo Rivas, the Principal Investigator of the Izana station. 

“I think it's a good opportunity for ICOS to widen the geographical coverage because we are in the subtropics, so our measurements are representative of subtropical conditions, which are not covered yet by any other ICOS station. Our measurements of atmospheric composition will definitely help the international community to fight climate change since they are representative of background conditions at a global scale,” adds Omaira Garcia, scientist at the Izana station.
