Europe's distributed atmospheric research infrastructure providing coordinated access to observation sites, simulation chambers, and air quality monitoring networks across 23 countries.
ACTRIS ERIC is the legal governing body of Europe's distributed atmospheric research infrastructure, providing scientists across the continent with coordinated access to atmospheric observation sites, simulation chambers, mobile research facilities, and central analytical laboratories. The organization manages a pan-European network that enables research on aerosols, clouds, trace gases, and air quality at a scale no single institution could achieve alone. Through its H2020 participation, ACTRIS ERIC has focused on both sustaining and expanding this infrastructure — improving access models, integrating with the European Open Science Cloud, and extending its capabilities to urban air quality monitoring. This dual mandate positions ACTRIS ERIC as both a research enabler and an active contributor to environmental monitoring and policy across Europe.
Both ATMO-ACCESS and RI-URBANS position ACTRIS ERIC as a core provider and operator of distributed atmospheric research facilities, covering observation sites, simulation chambers, mobile units, and central laboratories.
RI-URBANS directly targets reinforcing air quality monitoring in European urban areas, while ATMO-ACCESS underpins the broader monitoring network infrastructure.
ATMO-ACCESS explicitly addresses EOSC integration and sustainable access models — physical, remote, and virtual — for atmospheric research facilities.
RI-URBANS introduces urban-focused measurement capabilities around ultrafine particle characterization and source apportionment methodology.
RI-URBANS lists air quality policy as a direct keyword, signaling intent to connect scientific measurement with regulatory and public health applications.
With both projects beginning in 2021, temporal separation is limited — but the thematic split is instructive. ATMO-ACCESS focuses inward on the infrastructure itself: how to make atmospheric research facilities sustainably accessible through physical, remote, and virtual modalities, and how to connect them to EOSC. RI-URBANS represents an outward pivot, taking that same infrastructure capability and directing it at urgent, policy-relevant urban air quality challenges. The emergence of keywords like "source apportionment", "ultrafine particles", and "air quality policy" in the second project suggests ACTRIS ERIC is extending its mandate beyond facility provision into active scientific contribution to urban environmental monitoring.
ACTRIS ERIC is expanding from infrastructure management into applied urban air quality science, positioning itself as a bridge between European research networks and environmental regulators.
ACTRIS ERIC participates in large, multi-partner consortia rather than leading projects — a pattern consistent with its role as a pan-European infrastructure body that contributes resources and network access rather than project coordination. Despite holding no coordinator roles in these H2020 projects, its network reach is remarkable: 75 unique partners across 23 countries means it functions as a high-connectivity hub within atmospheric and environmental research consortia. Organizations seeking access to a distributed European measurement network should expect ACTRIS ERIC to be a well-connected, resource-rich partner rather than a project driver.
ACTRIS ERIC has worked with 75 unique consortium partners spanning 23 countries — an exceptionally broad network for an organization with only 2 recorded H2020 projects, reflecting its role as a continent-wide infrastructure backbone rather than a single research team. The network is primarily European but mirrors the international character of atmospheric science.
ACTRIS ERIC is not a research group that uses atmospheric infrastructure — it IS the infrastructure. As the legal ERIC entity, it holds the mandate and the distributed network of facilities that other atmospheric researchers across Europe depend on, giving it a structural position that no competing organization can replicate. For consortium builders, this means ACTRIS ERIC brings not just domain expertise but direct access to a coordinated system of observation sites, simulation chambers, mobile units, and open data services spanning the continent.
