The Spanish network participated in the meeting through in-person and online presentations, as well as by co-authoring numerous scientific contributions.
Members of ICOS-Spain participated in the ICOS Science Conference 2026, held from 15 to 17 September in Lund, Sweden, with online participation also available. Under the theme “Science, Data, Services: Together for Climate Action”, the meeting brought together the international community dedicated to greenhouse gas observations and the study of the carbon cycle.
The Spanish participation provided an opportunity to share results and activities linked to the network’s stations and projects. Ayoze Álvarez-Hernández gave an oral presentation on COCCON-Spain, a recently established observation network coordinated by the Izaña Atmospheric Research Centre — Emilio Cuevas. Its aim is to achieve broad coverage of atmospheric column observations across Spain, with a high degree of complementarity with ICOS-Spain’s in situ atmospheric measurements.
In the urban domain, Vanessa Monteiro presented a poster on characterising anthropogenic emissions through continuous atmospheric CO₂ observations in Barcelona. Her participation also showcased the development, together with the ICOS Cities Data Portal community, of open analysis tools that help other cities interpret their own observations.

José Antonio Adame (INTA) participated online with two posters: one examining the regional CO₂ and CH₄ sources influencing the coastal observatories of El Arenosillo and Capo Granitola, combining in situ measurements with simulations using the STILT atmospheric transport model; and another investigating methane variability and trends in the Atlantic–Mediterranean transition region using TROPOMI and GOSAT satellite observations.
In addition to the presentations, numerous ICOS-Spain researchers contributed as co-authors to studies on atmospheric observations, urban emissions and ecosystem carbon fluxes, listed at the end of this news article.
The conference provided an important forum for scientific exchange and discussion with the ICOS-ERIC community and other groups studying greenhouse gases and the carbon cycle. ICOS-Spain’s participation offered an opportunity to share experiences, raise the visibility of its teams’ work and explore new opportunities for collaboration.
