Aerosols, Clouds, and Trace gases Research InfraStructure - ACTRIS is a research infrastructure on the ESFRI roadmap from March 2016. ACTRIS is currently supported by the European Commission Horizon 2020 Research and Innovation Framework Programme (H2020-INFRAIA-2014-2015) from 1 May 2015 to 30 April 2019.
The objectives of ACTRIS Research Infrastructure
Detecting changes and trends in atmospheric composition and understanding their impact on the stratosphere and upper troposphere is necessary for establishing the scientific links and feedbacks between climate change and atmospheric composition.

Almost 135 different atmospheric variables are included in ACTRIS and about 70 sites are active.
The measurements are done with 30 different methodologies with time resolution ranging from seconds to 1 week.
European focus, but sites also north of 60 degrees (4 in operation) and one at Antarctica (Troll).
Zeppelin Observatory is the Arctic station. Several other stations at high latitudes; Finland (2), Sweden (2), Norway (1 in addition to Zeppelin). In total ca 70 stations submit data under ACTRIS.
Sites and distribution can be retrieved from here: http://actris.nilu.no
All data are available from the ACTRIS data portal: http://actris.nilu.no
The primary data are archived in 3 topic data bases:
- EBAS for ACTRIS near surface data (aerosol and reactive gases)
- EARLINET DB for ACTRIS aerosol profiles
- Cloudnet DB for ACTRIS cloud profile data
ACTRIS started in 2011, but is founded on earlier EU-projects hence the first data goes back to ca the year 2000, and gradually increasing since then.
The measurements are resulting from ca. 30 different methodologies: near surface measurements (both sampling and continuous measurements), profiles and total column, with time resolution ranging from seconds to 1 week.
Variables, procedures and methodologies are introduced in the ACTRIS Data Management Plan: http://www.actris.eu/Portals/46/Publications/DataCentre/ACTRIS_Data_Management_Plan.pdf. More Information is also available at ACTRIS web.
Comprehensive QA/QC procedures are implemented through a set of calibration centres, and the data centre. See ACTRIS Data Management Plan: http://www.actris.eu/Portals/46/Publications/DataCentre/ACTRIS_Data_Management_Plan.pdf, and contact also coordinators for more information.

No, but the project leads harmonisation efforts with GAW-WMO programmes on aerosols and reactive trace gases.
