ACTRIS is a European research infrastructure aiming to facilitate research and studies of aerosols, clouds and trace gases in the atmosphere.
ACTRIS’ main focus is to improve the understanding of how short-lived climate drivers affect each other, the climate, air pollution and human health.
Norway contributes strongly to ACTRIS; NILU manages the ACTRIS data center for the entire infrastructure, and Norwegian observatories supply a wide range of atmospheric measurements to ACTRIS.
The project ACTRIS-Norway started on 1 August 2022, with funding from the Norwegian Research Council's "National investment in research infrastructure".
ACTRIS-Norway will, among other things, make the sharing of climate and air pollution data easier and more user-friendly, while also increasing data quality.
ACTRIS-Norway are now in the middle of the project period and have already achieved several important milestones.
Among other things, a new ACTRIS data portal has been established, serving as the main access point for all ACTRIS data and data products, along with a virtual research environment (VRE) that provides examples of how ACTRIS data can be used in research and analysis.
Work is ongoing to make ACTRIS services and data even more accessible, both for Norwegian and international researchers.
The project will significantly upgrade the EBAS-database. EBAS handles all ACTRIS data measured at the ground.
Part of the work focuses on improved real-time data flow, as well as making data more FAIR.
In collaboration with the ACTRIS-Norway partners Meteorological Institute and CICERO, several combined data products have been and will continue to be developed.
The NILU-led ACTRIS data center contains data from European observatories, which are also part of global monitoring networks.
These observatories produce long-term time series based on strict operational standards.
There are around 80 ACTRIS observatories, three of which are Norwegian:
