Flux and concentration footprints

This special issue is comprised primarily of papers presented at 3rd INTAS (International Association for the promotion of co-operation with scientists from the New Independent States of the former Soviet Union) workshop on ‘‘Flux and Concentration Footprints’’ held at the Hyytiälä Forestry Field Station in Juupajoki, Finland. The workshop attracted scientists from ten countries and it was the final workshop of the project ‘‘Random walk models for the footprint problem in the turbulent atmosphere’’ funded by INTAS from 2000 to 2003. The seven research groups, involved in the project, came from Helsinki (Timo Vesala, University of Helsinki; coordinator), Novosibirsk (Karl Sabelfeld, Institute of Computational Mathematics and Mathematical Geophysics), Moscow (Vitaly Kukharets, Obukhov Institute of Atmospheric Physics), Ashgabad (Orazgeldy Kurbanmuradov, Physico-Technical Scientific Centre ‘‘Climate’’), Bayreuth (Thomas Foken, University of Bayreuth), Berlin (Wolfgang Wagner, Weierstrass Institute of Applied Analysis and Stochastics) and Roskilde (Niels-Otto Jensen, Risø National Laboratory). The present volume forms a collection of eight papers ranging from fundamental concepts to dispersion experiments.
