Eco-Meteorology group
Dr. Sung-Ching Lee
Mission
The Eco-Meteorology Group (Eco-Met) aims at improving the understanding of the interactions and feedbacks between climate, environmental changes, nutrient availability and the biogeochemical cycles of carbon, nitrogen, and phosphorus. To this end we combine tools and approaches from biometeorology and biogeochemistry such as eddy covariance flux observation, field manipulation experiments, soil and plant analysis, and proximal/remote sensing techniques. With a global focus, the group investigates the biosphere-atmosphere interactions by contributing to and analyzing globally distributed datasets (e.g. FLUXNET database, remote sensing products) using data-mining and model-data integration techniques. Exploiting this generalized information, our final goal is to enhance the description of the response of biosphere’s element cycling to climate variability in state-of-the-art global terrestrial biosphere models and up-scaling approaches.
Focus Areas
1. Semi-arid tree-grass ecosystem
Focus #1: Climatic and environmental controls on ecosystem-atmosphere energy and mass exchanges:
- Eddy covariance measurements of mass-energy exchanges between terrestrial ecosystems and the atmosphere at Majadas de Tiétar;
- Characterization and partitioning of water fluxes;
- Impacts of nutrient availability on carbon and water fluxes;
- Contribution to and analysis of large dataset (e.g. FLUXNET database);
Focus #2: Phenology and Ecosystem Processes
- Interactions and feedback between climate and land surface phenology;
- Understanding the relationship between phenology and water cycles;
- Development of tools for the measurements of land surface phenology;
Focus #3: Remote Sensing of Ecosystem Function
- Understanding the information about photosynthesis, ecosystem functioning and stress encoded into hyperspectral remote sensing observations and sun induced fluorescence (SIF);
- Evaluating factors affecting hyperspectral and SIF signals at different temporal scales;
- Evaluating drivers of the photosynthesis-SIF relationship in climate manipulation experiments;
2. Blue carbon ecosystem
Focus #1: Climatic and environmental controls on ecosystem-atmosphere energy and mass exchanges:
- Eddy covariance measurements of mass-energy exchanges (including methan fluxes) between terrestrial ecosystems and the atmosphere;
- Impacts of tidal actions on carbon and water fluxes;
- How vegetation ad microbe affect carbon and water fluxes, and how are they impacted by changes
- Contribution to and analysis of large dataset (e.g. FLUXNET database);
Focus #2: Dynamics and underlying mechanisms of lateral exchanges:
- Assessment of lateral carbon fluxes under different conditions using high-frequency measurement;
- Contribution of lateral exchanges in the net ecosystem carbon exchange;
- Understand composition of different sources of soil carbon storage (i.e., autochthonous and allochthonous inputs)
Focus #3: Modelling of flux and storage and estimates in a larger spatial scale
- Advancing process-based models for blue carbon dynamics;
- Combining machine learning techniques with process-based model;
- Using remote sensing products with best available model to provide robust regional/national/internation blue carbon budget
Recent News
October 2025
After summer, the Eco-Met group hosted a MSc student (Yu-Shan Sun) from Taiwan to investigate how fertilizer and water management affect greenhouse gas fluxes of rice paddy fields. Then we hosted the world famous biometeorologist, Dennis Baldocchi, at BGC for a 2-day symposium. Finally, the newcomers have all arrived in Jena, embarking new research topics!
Summer 2025
We had a fruitful week for the Germany-Taiwan project (Interactions between nutrient and carbon fluxes in agricultural ecosystems) funded by DAAD. A team from Taiwan, led by Cheng-Hsien Lin, stayed at for one week, having extensive exchanges and discussions via seminar, greenhouse experiment tour, and field visit! We will visit National Chung Hsing University at the end of this year. Stay tuned and we're keen to share what we do together.
Besides the DAAD project, the group has been active with many things in this summer! In the end of June, Stefan Metzger, Ph.D. visited us to coordinate with Bayu Hanggara PhD thesis. Then Nick went to University of St Andrews to teach a course in a blue summer school under C-BLUES EU framework. Right after that, Nick went all the way to Brisbane to attend the FLUXNET2025 conference and met many old and new flux friends. Since coming back to Jena, Nick and the group have been happily hosting visitors from around the world (Miko Kirchnaum from New Zealand and Vicente Burchard-Levine from Spain). Finally, Nick went to the Wadden Sea today with Lars Kutzbach at University of Hamburg and the national park staff to scout nice locations for new flux towers.
April 2025
Last week (28.04 to 02.05), the Eco-Met team was busy at the EGU 2025, but it was a very fruitful week. Nick co-convened a session on tropical forests (BG3.11) and a townhall on blue carbon (TM25). Group members including Sinikka, Bayu, Arvind, and Dan had great presentations in different sessions. Using this nice opportunity, we had a nice joint dinner with Prof. Dr. Dan Yakir's team to discuss future synergies. In addition, we also had wonderful interactions with scientists from FLUXNET, ECOSENSE, China, India (Dr. Sachchida Tripathi), and Taiwan forming further collaborations.
May 2022
The group has a new group leader!
To continue and re-design the successful research group Biosphere-Atmosphere Interactions and Experimentation previously led by Dr. Mirco Migliavacca (currently at the European Commission's Joint Research Centre) and Dr. Tarek El-Madany, Dr. Sung-Ching Lee joined the group as a new group leader. The new group will continue running the existing research site at Majadas de Tiétar, a semi-arid tree-grass ecosystem, and hence better understand the relevant understudied and unknown processes for dryland ecosystems.
Besides this, the new group has great interest in establishing coastal wetland (“Blue Carbon”) research in Germany, particularly in the Wadden Sea area. Unlike upland ecosystems, the exchanges between coastal ecosystems and the atmosphere are not only controlled by bio-meteorological variables but regulated by unique features such as salinity, tidal movements, and wind advections.
To reflect the new directions, the name of the group has been changed from Biosphere-Atmosphere Interactions and Experimentation (BAIE) to Eco-Meteorology (Eco-Met).
