Siberian tall tower inventory and monitoring project

Scientist(s): Christian Wirth (collaborator)

Funding: International Science & Technology Center (ISTC)

Duration: 2005-2007

Background: Within the project ZOTTO a tall tower of 300 m height is currently built in Central Siberia near the city of Zotino. The tower serves as a platform for concentration measurements of atmospheric trace gases. These data are used in atmospheric inversions studies to infer the distribution of carbon sinks and sources over Eurasia. Within the near footprint of the tower (radius 100 km) ground-based estimates of carbon stocks and fluxes are needed for bottom-up validation of inversion estimates.

Objectives: - Estimate C-stocks (above and belowground) and possibly NPP (above-ground only) at the landscape level - Quantify age-class distribution to detect changes in C-stocks at the landscape level that are driven by disturbance (age-dependence of processes along succession after fire and logging). - Monitor tree species-specific changes in recruitment, growth and mortality ("changes in successional pathways) with the help of permanent sample plots for repeated inventories of individuals trees - Provide initialization data (soils, hydrology, vegetation) and parameterization data (tree species) for regional succession and ecosystem modeling - Provide ground truth data in the first year for improving the remote sensing classification

Partners: Ernst-Detlef Schulze, Martin Heimann (MPI-BGC, ZOTTO), Evgenij Vaganov, Sergey Verkhovets, Anatoly Prokushkin (Sukachev Institut of Forest SB RAS, Krasnoyarsk), Anja Fankhänel (MPI-BGC)
