Atmosphere-Biosphere Coupling, Climate and Causality (ABC3)
Dr. Alexander J. Winkler
Mission
The Atmosphere-Biosphere Coupling, Climate and Causality research group focuses on identifying feedbacks and causal links in the exchange of carbon, water and energy fluxes between the terrestrial biosphere and atmosphere. In particular, we aim to understand how this coupled system changes under rising atmospheric CO2 concentration. We use models of varying complexity (conceptual models to fully coupled Earth system models) and combine our research with statistical analysis and modelling (machine learning to hybrid modelling) based on various Earth observation data streams.
Current key items of the ABC3 research group:
Methodological and Conceptual Approaches
- Exploring the application of modern machine learning / deep learning methods in Earth system research with a focus on obtaining interpretability to improve process understanding
- Developing hybrid-modelling approaches (i.e. theory-guided fusion of data-driven and mechanistic models) of land-atmosphere interactions
Overarching Research Objectives:
- Disentangling the different effects of rising atmospheric CO2 concentration and other confounding factors in Earth observations and model simulations using causal inference
- Understanding the causal drivers of phenological changes in in-situ and satellite observations and identify the biogeophysical and biogeochemical feedbacks to the climate system
- Isolating and quantifying direct and indirect effects in the atmosphere-biosphere coupling in controlling anomalies in carbon fixation
- Determining constraints of key entities in the carbon cycle climate system by linking multi-model ensemble simulations and observational data
