The World Meteorological Organization’s Global Atmosphere Watch (WMO GAW) published new measurement guidelines for observations of carbon dioxide, methane and nitrous oxide.
ICOS expertise and experiences in setting up the station network and protocols were major contributors to the final guidelines.
The year 2025 saw ICOS data being used in a broad range of scientific studies. Researchers used ICOS data, tools and expertise to address all kinds of scientific questions, from improving estimates of urban and national greenhouse gas emissions, to comparing instruments for ocean carbon measurements, to mapping out how the network could improve and expand in the future.
