Partner 17 - UHel
University of Helsinki (UHel)
Expertise and experience of the organization
The Department of Physical Sciences at the UHel has
over 25 years tradition in atmospheric research. 60 scientists and doctoral
students are currently engaged in this area. The main research subjects are
aerosol dynamics (nucleation, condensation, coagulation, deposition), formation
and growth of atmospheric aerosol particles and cloud droplets, atmospheric
chemistry, urban aerosols, forest-atmosphere interactions (fluxes, photosynthesis,
water transport), aerosol-cloud-climate interactions, atmospheric boundary-layer
theory, modelling and parameterization. The basic theoretical resources consist
of detailed computer codes describing basic phenomena such as multi-component
nucleation and condensation, photosynthesis, and of extensive model for aerosol
dynamics, atmospheric chemistry and cloud microphysics. The basic experimental
resources consist of three field stations (SMEAR : I, II, Urban) and a state-of-art
aerosol laboratory. In the field stations e.g. aerosol dynamics, atmospheric
chemistry, micrometeorology, gas exchange between forest and atmosphere,
soil chemistry and forest growth are measured continuously.
Role and contribution
UHel is responsible for the aerosol science aspects
including aerosol-climate interaction, ground based observations and remote
sensing, and for development of improved parameterization of the turbulent
and mean structures of UABLs for use in climate and air quality models.
