12th TERENO WORKSHOP 2024

At the beginning of November 2024, the TERENO initiative hosted its annual international workshop. Around 90 experts from various countries and scientific disciplines came to the Helmholtz Center for Environmental Research - UFZ in Leipzig to discuss the latest developments in terrestrial environmental research. The focus was on innovative approaches to observing and modeling environmental processes, interdisciplinary cooperation and the expansion of international networks. Inspiring presentations, intensive discussions and practical workshops promoted exchange and provided valuable impetus for future research projects. The program also included two excursions: to the Leipzig branch of the German Meteorological Service (DWD) and to the Brandis lysimeter facility (right picture). The Brandis Lysimeter facility has been providing data on soil water balance since 1980 and is part of the monitoring network of the Saxon State Agency for Environment, Agriculture and Geology.

 

 

 

Second TERENO-OZCAR International Conference 2023
in Bonn, Germany

 

Sessions Posters Impressions

 

In October 2021, we organized the first joint meeting of OZCAR, the French research infrastructure on “Observatoires de la Zone Critique” and TERENO, “Terrestrial Environmental Observatories” in Straßbourg, France. It was the first meeting of this kind in Europe aiming at bringing together scientists active in terrestrial system’s research. This meeting was extremely well received as the place to be where critical zone research in Europe meets.

Following up on this success, it was decided to organize a second international joint meeting in Bonn, the former capital of the Federal Republic of Germany. The conference program covered 10 main subject areas – from fundamental questions on exchange processes between soil, vegetation and atmosphere, to the use of data and different approaches to long-term observation, to new measurement methods and modeling approaches. Some 170 researchers from about 20 countries attended the conference in Bonn and roughly, 50 additional participants attended the conference online. More than 80 oral presentations and 70 poster presentations brought participants up to date on the latest developments in Critical Zone research.

An excursion to the TERENO test site Wüstebach and a conference dinner on the Rhine cruise ship Moby Dick complemented the conference. In addition, Franco-German research and science cooperation and related funding and financing programs were presented and discussed at a special event hosted by Samuel Pujade-Renaud of the French Embassy in Germany.

12th TERENO WORKSHOP:
FROM OBSERVATIONS TO MODELLING

 

About 70 experts met in Garmisch-Partenkirchen from 8 to 11 November 2022 for the 12th TERENO Workshop. The event, organised by Karlsruhe Institute of Technology’s Institute for Meteorology and Climate Research (IMK-IFU), was held under the motto „From Observation to Modelling“.

 

With its annual workshop, the TERENO initiative offered participants an opportunity to exchange ideas with each other as well as with national and international partners. This was greatly appreciated all around, especially after the Corona break. After more than a decade of measurements, their integration into hydrological, biogeochemical and biodiversity modelling was presented and discussed in expert lectures and workshops. The focus was not only on measurements from the various TERENO observatories, but also from other observatories.

 


 

After the opening by Prof. Hans Peter Schmid, Director of IMK-IFU, and the report by Prof. Harry Vereecken on TERENO highlight activities in 2022, a broad spectrum of technical presentations was on the programme. Different approaches at site, catchment, regional and national scales were presented, such as the use of remote sensing and process-based models as well as AI applications for hydrological and bio-geochemical issues. The implementation of measurement and simulation results into decision support tools and products for stakeholders was also discussed, especially with regard to sustainable agriculture.

 

For the first time, the TERENO workshops hosted a cross-Helmholtz exchange between engineers, technicians and scientists, with keynote speeches and lively discussions on the topic of sensor data workflow and quality control and assurance. Due to the very positive experience, this is to become a fixed component of the annual TERENO workshops in the future.

 

During the workshop, the TERENO advisory board, composed of independent scientists, also met and praised the TERENO research, which in their view has been very successful.

Joint conference of OZCAR and TERENO in 2021

By Heye Bogena and Isabelle Braud


The first OZCAR-TERENO international conference jointly organized by the French research network OZCAR and TERENO took place from October 5 – 7, 2021 in Strasbourg, France. About 190 on-site participants and more than 100 virtual participants attended the conference. In total, the conference featured more than 70 oral presentations and 100 poster presentations. All participants saw the hybrid conference as a great success.

 

 

The focus of the conference was research of the Critical Zone, the thin layer of our planet from the top of the vegetation canopy down to the groundwater. A major role in Critical Zone research is the multidisciplinary, highly instrumented observatories that are part of the TERENO and OZCAR networks. The conference was also supported from the European research infrastructure eLTER (Long-Term Ecosystem, Critical Zone and Socio-Ecological Research Infrastructure).


The conference program spans 17 main subject areas, spanning fundamental questions on exchange processes between soil, vegetation and atmosphere, the use of data, and new measurement methods and modeling approaches. Topics included how observatories take different approaches to long-term environmental and biodiversity observation, the integration of in-situ and remote sensing data, and innovative sensing methods for researching the Critical Zone.
The first OZCAR-TERENO conference marks the continuation of a series of international conferences hosted by TERENO – in 2014 in Bonn and 2018 in Berlin. In the future, the OZCAR-TERENO conference will take place every two years, alternating between France and Germany.

 

 

Successful start


Some 200 researchers came together in Strasbourg, France in early October 2021 to take part in the first OZCAR-TERENO international conference. Roughly 100 additional participants attended the conference online. Whether in person or virtually, more than 70 oral presentations and 100 poster presentations brought participants up to date on the latest developments in Critical Zone research.


The Critical Zone is the thin, outer layer of our planet – the Earth’s “skin” – from the top of the vegetation canopy down to the groundwater. The complex exchange processes in the Critical Zone – between rock, soil, water, atmosphere and living organisms – create the foundation for all life on Earth. Key to Critical Zone research are the multidisciplinary, highly instrumented observatories operated by the two hosts of the conference: TERENO and the French research infrastructure “Observatoires de la Zone Critique: Applications et Recherche”, a.k.a. OZCAR. The conference program covered 17 main subject areas – from fundamental questions on exchange processes between soil, vegetation and atmosphere, to the use of data and different approaches to long-term observation, to new measurement methods and modeling approaches.


Prof. Markus Reichstein from the Max-Planck-Institute for Biogeochemistry in Jena, in his presentation “Extracting information from ecosystem time-series using a hybrid machine-learningmodelling approach” suggested that a stronger integration of observation and (mechanistic) models is needed for a better understanding of the Earth system. He proposes a fusion of machine learning and mechanistic modelling approaches into so-called hybrid modelling – a combination that could allow for better predictions and better understanding of the system, e.g. by inferring unobserved variables. In his presentation, Reichstein explained the concept using an example for the carbon
cycle at site level and one for the global water cycle. In the global water cycle example, a conceptual hydrological model builds the physical basis, where e.g. partitioning coefficients are estimated spatio-temporally with a deep learning approach* and a multi-task learning approach takes into account the multiple-constraints of evapotranspiration, terrestrial water storage, runoff and snow water equivalent.


Also promising were the new insights on bedrock water storage shared by Dr. Daniella Rempe from the University of Texas (Austin) in her presentation “The bedrock component of watershed storage: Advances and insights”. While dynamic water storage plays a central role in determining how watersheds respond to change, this role remains uncertain, largely because relatively little research has been conducted thus far on water storage in bedrock (as compared to research on soils and groundwater). Fortunately, this is changing thanks to recent advances in monitoring. Direct measurements indicate that bedrock water storage substantially contributes to transpiration fluxes, and also influences the timing and volume of groundwater recharge and streamflow. Furthermore, new studies indicate that plants access water stored in bedrock both within and outside of drought periods. “Together, these findings have consequences for how we conceptualize a wide array of Critical Zone processes,” says Rempe.


In her presentation “From Sensor to Real-Time Forecasts: Setup of a Cosmic-Ray Neutron Sensor Network for Data Assimilation and Optimization of High-Resolution Real-Time Predictions of Soil Moisture”, Dr. Patrizia Ney from Forschungszentrum Jülich showed how forecasts can be generated from sensor data in real time. For their project known as ADAPTER (see also TERENO Newsletter 2021-1), Jülich researchers installed a permanent network of twelve hydrometeorological measurement systems at twelve selected agricultural field sites in Germany’s state of North RhineWestphalia. The measurement systems are fitted with a multifunction weather station as well as
with cosmic ray neutron sensors, which provide data on current soil moisture levels. The field measurements are also fed into a land-surface hydrological model, which can generate prototypicalforecasts for parameters such as plant-available water – in real time and for each specific parcel of land. The information is intended primarily to help farmers make their operations more sustainable and resilient against extreme weather, such as droughts.


The next OZCAR-TERENO conference is scheduled for 2023 in Germany.
