ACTRIS creates excellent science in the field of atmospheric and Earth climate research. ACTRIS has roots in a decade-long European wide cooperation in large projects and it builds on efforts such as EARLINET, EUSAAR/CREATE and CLOUDNET.  

In the last 10 years, ACTRIS cooperation has resulted in more than:

  • 8,000 scientific papers and 100 book chapters.
  • 900 Masters and PhD students carried out part of their research,
  • 2,200 graduates received training in ACTRIS infrastructures.

Even more important is the impact of scientific activities: new patents, methodologies, prototypes, and instrument designs have been developed within ACTRIS frame to motivate new methods for air quality control and to improve risk management assessments.

ACTRIS data has been used to evaluate global and regional emission inventories for key natural and anthropogenic species, to measure atmospheric concentration trends, to simulate different atmospheric conditions to better quantify processes from nanoscale to macro-scale, to provide regional air- quality, numerical weather prediction, and climate models with the necessary information for assimilation or validation and testing, to complete observation from space for many different applications and to evaluate the effectiveness of public policies. for example, the equivalent of approximately 18,000 years of measurements has been delivered as a tailored service for Copernicus model validation.

ACTRIS provides an enabling environment for new opportunities of innovation and transfer of knowledge with industry (including SMEs). Far from being just a provider, the industry turns into a real RI user and innovation co-developer thanks to collaborations and services accessed through the SAMU. 

ACTRIS facilities can provide unique insights into new or existing products, help resolve technical uncertainties, and enable innovation, thus supporting pre-competitive and pre-commercial R&D. European, national and international businesses take advantage of experimental test sites and calibration centers for advancing their knowledge-based activities.

This leads to the development of new products and innovative services in the environmental field. A potential large market exists in Europe for improving air pollution control and monitoring, use of renewable energy, and developing cost-effective and innovative instrumentation. 

Moreover, the use of ACTRIS data has a potential impact in different sectors in terms of services: 

  • food security, 
  • tourism,
  • water access, 
  • agriculture and farming, 
  • public health, 
  • protection from risks related to climate change, and 
  • resilience of territories.

In these sectors, science and technology will intersect, and research results will be transferred to industry and converted into competitive applications, in addition to promoting new qualified ancillary industries, knowledge spillover, and industrial spin-offs.

Services offered by ACTRIS to support innovation foster knowledge transfer, which aims in the medium to long term to create both technological and societal breakthroughs and impact in said sectors and beyond. ACTRIS services for innovation include:

  •  training on-demand or targeting specific user groups; 
  •  the design and co-design of instrumentation, equipment or procedures, 
  •  exploration of instrument synergies, and new innovative research capabilities.
  •  joint research activities 
  •  joint instruments testing. 
  •  development of new observation techniques for aerosol, clouds, and reactive trace gases; 
  •  improvement of measurement and retrieval methodologies for aerosol, clouds, and reactive trace gases.
