The ACTRIS Network of Stations Minimize
The ACTRIS research infrastructure merges four measurement networks:
  1. The European Aerosol Research Lidar Network for remote sensing of the vertical aerosol distribution (EARLINET) which includes 27 lidar stations (Raman lidar stations, multi-wave Raman lidar stations, back-scatter raman lidar stations).
  2. The European Supersites for Atmospheric Aerosol research for in-situ measurements of chemical, physical and optical properties of aerosols (EUSAAR) including ground-based EUSAAR stations and contribution stations.
  3. A ground-based monitoring capacity for short-lived trace gases.
  4. A distributed infrastructure for clouds and aerosol quality-controlled observations with cloud profile sites.


ACTRIS sites reporting QA data to the ACTRIS Data Centre (June 2014)

The networks provide consistent datasets of observations which are made using state-of-the-art measurement technology and data processing. Many of the stations from the different networks are co-located with or close to remote sensing and in-situ instrumentation. The data is available through the ACTRIS data portal.
