PEEX: Pioneers in atmospheric science

The Pan Eurasian Experiment (PEEX) contributes to Finland’s Centres of Excellence in Research (FCoE), which are the flagships of Finnish science policy

PEEX is a multidisciplinary climate change, air quality, environment and research infrastructure programme focused on the northern Eurasian regions, particularly the Arctic and boreal regions.

It is a bottom up initiative by several European, Russian and Chinese research organisations and institutions. PEEX is open for new institutes to join in.

FCoEs are granted by the Academy of Finland and are intended for the research teams and their consortia to carry out research at the highest level.

The FCoE in physics, chemistry, biology and meteorology of atmospheric composition and climate change originates from the early 1980s, when scientists from the Department of Physics and Department of Forest Ecology at the University of Helsinki created a multidisciplinary team and started to unravel questions related to biosphere-atmosphere interactions.

The Centre of Excellence in Atmospheric Science – From Molecular and Biological processes to the Global Climate (ATM) originates from early 1980’s, when scientists from the Department of Physics and the Department of Forest Ecology at the University of Helsinki created a multidisciplinary team and started to unravel questions related to biosphere-atmosphere interactions.

The PEEX programme and research agenda

The PEEX programme agenda is divided into four focus areas:

  • Research agenda,
  • Infrastructures,
  • Impact on society, and
  • Knowledge Transfer (PEEX Science Plan).

Aims of PEEX research agenda:

  • To understand the Earth system and the influence of environmental and societal changes in pristine and industrialised Pan-Eurasian environments (system understanding).
  • To determine the processes relevant to climate change, demographic development and use of energy resources in the Arctic-boreal regions (process understanding).

Our main objective is to reduce the scientific uncertainties related to climate change at global scale by quantifying the essential feedback mechanisms between the atmospheric processes and changing functioning of biosphere.

PEEX objectives

Our main scientific objective is to quantify the feedbacks between the atmospheric processes and changing functions of the biosphere in a changing climate. In order to do this, we will:

  • Find out and quantify the main climatic feedbacks and forcing mechanisms related to aerosols, clouds, precipitation, biosphere-atmosphere and cryosphere-atmosphere interactions;
  • Develop, refine and utilise the newest measurement techniques and modelling tools, scaling from quantum chemistry to global Earth System Observations and Models;
  • Create a deep and quantitative understanding on the role of atmospheric clusters and aerosol particles in local and global biogeochemical cycles of water, carbon, sulfur and nitrogen and their linkages to the atmospheric chemistry; and
  • Integrate the results in the context of regional and global scale Earth system understanding.
RESEARCH INTERESTS

PEEX’s multidisciplined experts

Our multidisciplinary research team includes 235 scientists working in the fields of physics, chemistry, biology and meteorology at the Universities of Helsinki and Eastern Finland (Kuopio), and at the Finnish Meteorological Institute.

Our work is based on a network of field stations producing extensive long-term data on atmospheric properties and ecological mass fluxes in different types of environments and regions, including Arctic, boreal and tropical ecosystems, and on focused experiments and modeling aimed at understanding the observed patterns.

We have been awarded with the Academy of Finland CoE status three times since 2002 and the Nordic CoE status in 2003 and 2010.
