Research Focus:

• Feedback processes between terrestrial ecosystem functionality and climate change
• Observation of greenhouse gas exchange processes with interdisciplinary approaches
• Assimilation of datasets covering multiple spatiotemporal scales into modeling frameworks

Research Interests:

My research interests focus on the design of networks of greenhouse gas observation systems covering multiple spatiotemporal scales, and the assimilation of these new datasets into flexible modeling frameworks. One major focus is placed on approaches to optimize a hierarchy of observation platforms across scales to constrain surface-atmosphere exchange fluxes of unknown, but presumably highly variable spatiotemporal distribution (e.g. methane fluxes in permafrost ecosystems). A second major focus, directly related to the first, is to mine all information available on ecosystem feedbacks to climate variability, ranging from small scale soil chambers to large scale satellite data, from high-frequency eddy-covariance data to long-term biometric inventories, in order to improve the representation of underlying mechanisms in process models.

Research Activities:

Permafrost monitoring in Northeast Siberia
In summer 2013, our group established a new monitoring site to capture greenhouse gas exchange fluxes between permafrost ecosystems and the atmosphere near Chersky, Northeast Siberia. Instruments were installed on a wet tussock tundra in the floodplain of the Kolyma river, about 15km south of town. For a disturbed site (drainage since 2004) and an undisturbed reference, exchange fluxes of CH4 and CO2 are measured with 2 eddy-covariance towers and 20 closed soil chamber systems. All instruments are set up to provide year-round observations of greenhouse gas flux exchange patterns.

Regional scale inverse modeling of carbon budgets in the Pacific Northwest US
In collaboration with colleagues from Oregon State University, I am testing and evaluating conceptual strategies to handle the assimilation of various data sources into atmospheric inverse modeling frameworks, including geostatistical inverse modeling approaches. The database in this domain is provided by a network of currently seven observation towers, the tallest of which reaches 283 m a.g.l., which as been set up to monitor mixing ratio time series of CO2 and CO in an effort to constrain biosphere and anthropogenic Carbon budgets.

Surface Monitoring Verification and Accounting of Carbon Capture and Storage (CCS) facilities
Together with a team of scientists based at St.Francis Xavier University, Canada, I am involved in a pilot project focusing on two CCS sites in Canada where several surface based monitoring approaches will be tested, evaluated and finally integrated into a comprehensive network. This research aims at providing a tool to detect potential leaks, thus verifying how much of the injected greenhouse gas actually stays underground.
