Eco-Meteorology group

Eco-Meteorology group

Dr. Sung-Ching Lee


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

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;
  • 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;

Recent News

April 2024

The end of 2023, Nick gave a keynote talk on "Power of long-term flux observation and synergies in land-atmosphere interactions” at Asiaflux 2023 in Jeju, Korea.
We had finally a chance to have a full group dinner in March, before the Science Adivosry Board meeting! Updated team photo is the Team tab.
Also, the new EU project, C-BLUES, started on April 1! There'll be more new group members joining us, stay tuned.
This month, Nick is teaching a MSc course on Land-Atmosphere Interactions at University of Freiburg. Laura and Nick will attend the EGU24 in Vienna!

October 2023

October was a busy month for the group!
First of all, Sinikka published a preprint on “Interpretability of negative latent heat fluxes from Eddy Covariance measurements during dry conditions”.
Laura attended the TERENO conference in Bonn to show some preliminary results of her first PhD project.
Bayu joined the group, and visited Majadas de Tiétar with Laura and the Fieldwork team.
Lastly, Nick secured a Horizon Europe project on blue carbon ecosystems (details coming soon!), and will give a keynote talk at Asiaflux 2023.

September 2023

On August 30, our BGI department held annual retreat and it was the first time that Laura and Arvind presented posters showing their PhD projects, exciting! Also, our group hosted a visitor, Alex, from PSInet. We discussed how water potential information can help us understand better about plant responses to drought and heat stress. And, Sinikka will supervise a BSc student to establish soil retention curve for Majadas de Tiétar. This will allow us to convert long-term soil water content measurements to soil water potential, and hence to better simulate C fluxes under dry conditions.

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-MadanyDr. 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).





MANIP, a long term experimental project, aims at understanding responses in different eddy covariance sites from nutrient loading (primarily N and P) and water availability, on ecosystem-level carbon, water fluxes, and their interannual variability.
The SMANIE project is a small-scale manipulation experiment (SMANIE) running parallel to the large scale manipulation experiment with focusing on the grass layer. more
LFT: Long-term fate of N from fertilizer experiment
The LTF or “Long-Term Fate” experiment aims to answer that question by tracking the fate of added nitrogen fertilizer for one year after application. more
