ACTRIS - A general description

ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure) is a pan-European initiative consolidating actions amongst European partners producing high-quality observations of aerosols, clouds and trace gases. Different atmospheric processes are increasingly in the focus of many societal and environmental challenges, such as air quality, health, sustainability and climate change. ACTRIS aims to contribute in the resolving of such challenges by providing a platform for researchers to combine their efforts more effectively, and by providing observational data of aerosols, clouds and trace gases openly to anyone who might want to use them.

Currently the coordination of ACTRIS is supported by two different EC-projects; ACTRIS-2 and ACTRIS Preparatory Phase Project (PPP). The former revolves around the on-going research, coordinating efforts of partner organisations and producing observations and data, while the latter is a project aiming to establish a research infrastructure with its own legal entity and operational structure that will carry on the work done by ACTRIS-2. EUROCHAMP-2020 is a separately run project coordinating the activities of atmospheric measurement chambers in Europe, but aims to merge in ACTRIS at the end of the project. Figure below describes the different parts and phases in ACTRIS preparations, and their relations with each other.

The roadmap to make ACTRIS an operating  research infrastructure by 2025.

ACTRIS was accepted into ESFRI (The European Strategy Forum on Research Infrastructure) Roadmap in 2016. This means that ACTRIS has been identified as a new important pan-European research infrastructure, and that it has been deemed to be mature enough to be operational within the next ten years. The supporting role of ACTRIS PPP is crucial in achieving this.
