The atmosphere is a highly complex system driven by countless chemical and physical processes. Atmospheric process understanding and predictions use complex models that are underpinned by observations. Without high-quality observation data to constrain predictive models, any forecast of the atmosphere is highly unreliable. 

ACTRIS contributes:

  • to reducing uncertainties in emission sources, to understanding deposition processes that remove short-lived constituents from the atmosphere and to quantify their potential impacts on ecosystems.
  • by bringing essential information for understanding global biogeochemical interactions between the atmosphere and ecosystems, and how climate-ecosystem feedback loops may change atmospheric composition in the future.
  • by supporting the development of the required level of understanding of sources of the air pollutants that negatively affect human health.
  • with the necessary observations to complement Earth Observations from space, providing unique ground-truthing of remote sensing information collected by current and future satellite missions.

ACTRIS helps responding to the grand-challenges faced nowadays by our society: ACTRIS enables a deeper understanding in atmospheric processes, improving our resiliency to climate change, and air quality, contributing to reduce the effects of air pollution on public health and ecosystems
