ATMO-SERV · ATMOspheric research infrastructure SERVices for curiosity-driven research of atmospheric chemistry and dynamics

ATMO-SERV brings together all European atmospheric Research Infrastructures (RIs) – ACTRIS, ICOS, IAGOS, EISCAT_3D and SIOS – complemented by the ARISE and ASCENT networks, the health-focused EIRENE RI, and international access providers in South Africa, India, Lebanon, Brazil and the USA. For the first time, this unique consortium integrates the full spectrum of atmospheric observations, from the Earth’s surface to the upper atmosphere, as well as the human exposure research, addressing the intertwined challenges of climate change, air quality, extreme events and health impacts. The project provides curiosity-driven transnational and virtual access to over 90 state-of-the-art facilities and 12 digital services, with harmonised access management via the ACTRIS Service and Access Management Unit. Users will benefit from integrated, interoperable and FAIR services spanning simulation chambers, airborne facilities, observation networks, laboratories, data repositories and digital tools. ATMO-SERV targets knowledge gaps in chemical mechanisms, atmospheric layers and their coupling, and exposure pathways that underpin climate and health assessments – specifically in (1) chemistry of emissions; (2) aerosol formation, multiphase processes, and aerosol-cloud-precipitation interactions; (3) atmospheric dynamics and chemistry at interfaces between atmospheric layers; and (4) air pollution, exposome and human health linkages. The ATMO-SERV project strengthens the European leadership in atmospheric sciences by ensuring integration into global observing systems and by supporting calibration and validation of satellite missions. Training and outreach activities will engage new users, support widening countries and empower the next generation of researchers. By fostering open, sustainable and globally connected access to RIs, ATMO-SERV will advance frontier knowledge, generate scientific breakthroughs that benefit science, policy and society in Europe and worldwide.
