ACTRIS Europe

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 ACTRIS Science Community unites partners from 22 countries across Europe and involves more than 100 research institutes and organisations.

Objectives of ACTRIS

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. 

  • 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 second objective is to provide effective access to this information and the means to more efficiently use the complex and multi-scale ACTRIS parameters serving a vast community of users working on models, satellite retrievals, and analysis and forecast systems.
  • The third objective is to raise the level of technology used in the RI and the quality of services offered to the community of users, involving partners from the private sector.
  • Finally, the fourth objective of ACTRIS is to promote training of operators and users and enhance the linkage between research, education and innovation in the field of atmospheric science.

Institute of Electrical Measurement and Sensor Systems - Sensor Systems and Sensor Physics

The Institute of Electrical Measurement and Sensor Systems (EMS) at Graz University of Technology significantly contributes to the ACTRIS network through advanced sensing technologies for aerosols and gases. The Sensor Systems and Sensor Physics, and Photonic Sensors groups specialize in developing adapted measurement systems for environmental monitoring, air quality assessment, traffic pollution measurement, and icing cloud characterization.

Their research includes technologies such as photoacoustic spectroscopy, condensation particle counters, optical particle detection, and electrical particle detection. EMS operates a well-equipped aerosol reference laboratory with state-of-the-art instruments like the Jing miniCAST, TSI SMPS, and custom-made aerosol generators. They focus on improving aerosol and gas sensors for specific environments, such as traffic-related emissions and environmental trace gas quantification through laser-based techniques like TDLAS and PAS.

EMS also advances cloud characterization, particularly the measurement of liquid and ice water content in clouds, supported by in-house calibration tools. Their capabilities extend to complete sensor system design, including signal processing, hardware design, and system calibration.

Role in ACTRIS:

  • development of advanced sensor techniques
  • traffic pollution measurement
  • aerosol reference laboratory

Retrievals:

  • in situ aerosol and trace gase measurements
  • in situ cloud (liquid and ice water content) measurements

    Lab calibration of a Pandora



    Vienna University of Technology (TU Wien)

    TU Wien has concentrated its research in five research focal areas (and one additional field) – one of them being Energy and Environment, where emphasis is set on interdisciplinary research and cross-linking of activities of research groups. Generally, research activities linked to ACTRIS contribute to the research field ‘Environmental Monitoring and Climate Adaption’.

    ACTRIS connects projects carried out within the research units or groups Environmental Analytics, Physical Chemistry of the Atmosphere Water Quality Management, Geophysics, This can be visualized via recent activities at the Sonnblick Observatory. Research at this high mountain site allows the characterization of background conditions above Europe, to identify long range transport of natural or anthropogenic pollution events and to investigate basic and applied research questions related to atmospheric processes and deposition. 

    Present research projects comprise aerosol characterization, ice nucleation, wet deposition and permafrost monitoring. 

    Role in ACTRIS:

    • Coordinator within ACTRIS Austria
    • Contributions to aerosol and cloud measurements at Sonnblick

    Retrievals:

      • Aerosol parameter
      • Cloud and precipitation measurements
