ACTRIS-2 (Aerosols, Clouds, and Trace gases Research InfraStructure) is a European Project supported by the European Commission Horizon 2020 Research and Innovation Framework Programme (H2020-INFRAIA-2014-2015) from 1 May 2015 to 30 April 2019.
ACTRIS is the European Research Infrastructure for the observation of Aerosol, Clouds, and Trace gases. ACTRIS is composed of observing stations, exploratory platforms, instruments calibration centres, and a data centre. ACTRIS serves a vast community working on models and forecast systems by offering high quality data for atmospheric gases, clouds, and trace gases. The primary objective of ACTRIS is to provide the 4D-variability of clouds and of the physical, optical and chemical properties of short-lived atmospheric species, from the surface throughout the troposphere to the stratosphere, with the required level of precision, coherence and integration. The EGAR research group provides high quality, quality assured and quality checked data on aerosol chemical and physical properties measured at Montseny and Montsec sites since 2002.
ACTRIS 2 is coordinated
