Project summary

The goal of the collaborator proposal presented here is to take advantage of and to complement tall mast observations proposed within the framework of a parallel ISTC partner proposal with (1) measurements of reactive components of the atmosphere and aerosols during two winter and two summer campaigns and (2) regular measurements of ozone, nitrogen oxides, aerosol characteristics and ecosystem parameters. The proposed measurements will take place either directly at the mast or within its footprint. The regular measurements will extend over a period of three years. The campaigns will be performed by the Obukhov Institute for Atmospheric Physics, Moscow and the Max-Planck Institute for Chemistry, Mainz and the regular atmospheric chemistry and ecosystem measurements will be performed by the Sukachev Institute of Forest in Krasnojarsk, the Obukhov Institute of Atmospheric Physics, Moscow, and the Max-Planck Institute for Biogeochemistry, Jena. The purpose of the parallel tall mast project is to observe ecosystem changes in a changing climate as documented by many independent observations.

The scientific purpose of the reactive chemistry measurements proposed here is (1) to characterize the state and main controls of the chemistry of the lower troposphere in a remote northern high latitude region during the summer and winter seasons, (2) to understand the role of polluted air transported from Central European and of atmospheric constituents from forest fires for lower tropospheric chemistry in Siberia, (3) to determine the role played by synoptic and larger-scale meteorological processes on the budget of trace gases and aerosols in near-surface air and (4) to study land-biosphere tropospheric chemistry interactions mediated through VOCs emitted from the tree canopies. The concentration and ecosystem measurements within the surroundings of the mast finally are designed to help interpret and ground truth the tall mast measurements in terms of the underlying changes of the Siberian ecosystem. The analysis and synthesis of the data will be conducted with the same modeling tools proposed in the parallel tall mast proposal. These are state-of-the-art numerical models of photochemistry, biogeochemistry and climate.
