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. 

The Greek component of ACTRIS is the PANACEA-RI. PANGEA, the Pan-Hellenic Geophysical Observatory of Antikythera of NOA will strengthen the ACTRIS component in Greece in the near future, stay tuned!
