NEWS: New Collaborative Research Center (CRC) at University of Bonn
A new Collaborative Research Centre (CRC) at the University of Bonn with strong connection to CESOC (the speaker is one of the founding directors of CESOC: Prof. Jürgen Kusche) will be established for 4 years from 1 January 2022 onwards, funded with almost 10 million euros by the German Research Foundation (DFG):
The CRC1502 “Regional Climate Change: The Role of Land Use and Water Management”.
Man-made climate change has already increased the frequency of extreme events such as heat waves, droughts and heavy precipitation – experts predict a continuation of this trend for the rest of the 21st century. “The consequences of this, for example drying out soils in some regions and increasing flooding in others, threaten the coexistence and existence of future generations,” says Prof. Dr. Jürgen Kusche from the Institute of Geodesy and Geoinformation at the University of Bonn, speaker of the new Collaborative Research Center. “They pose significant risks, including to sustainable agricultural production and thus to food supplies.”
The far-reaching influence of climate gases, especially CO2 and methane, on the global climate is undisputed. In the Collaborative Research Center 1502 “Regional Climate Change: The Role of Land Use and Water Management,” the researchers investigate the hypothesis that human-induced land use change and intensified water management also influence regional climate – leading to unintended changes in the natural regional water and energy cycle. The hypothesis to be investigated in the CRC even goes so far as to suggest that such changes have already contributed significantly to the observed trends in the regional water cycle.
To investigate this hypothesis further, researchers from a wide range of disciplines come together – including hydrology, meteorology, geodesy, earth system modeling, remote sensing, agricultural economics and social sciences. Together, they aim to develop a model system that will be able to map, in particular, those human-climate interactions associated with changes in the continental hydrological cycle. The project groups of the CRC will initially focus on Europe in the first, four-year funding phase. The goal is to develop a coupled model system that will map not only the dynamics of the individual components of the Earth system, but also their interactions with each other, and will serve in particular to quantify human-induced influences on the natural regional water cycle. “Our research results achieved in the CRC will serve as a basis for the development of criteria for sustainable land and water use, in terms of the regional climate,” Jürgen Kusche emphasizes.
Other partners include Forschungszentrum Jülich, Deutscher Wetterdienst (DWD) and the Universities of Cologne and Göttingen.
The Collaborative Research Center is thematically embedded in the Transdisciplinary Research Areas “Modeling” and “Sustainable Futures” of the University of Bonn.
Funding amount:
almost 10 million euros

TALK: Climate@EUMETSAT: Systematic Support to Climate Science and Services
Dr. Jörg Schulz, Eumetsat, Darmstadt
12 April 2021, open talk as pdf
Since about 10 years, EUMETSAT is systematically utilising the maintained unique archive of space-based observations collected by missions exploited by EUMETSAT and partners for the production of consistent fundamental climate data records through re-calibration of space-based observations and reprocessing of associated long series of physical variables and climate data records of geophysical essential climate variables. EUMETSAT contributed to several EU research projects ERA-CLIM, ERA-CLIM2, QA4ECV, FIDUCEO, and GAIA-CLIM making significant progress in the understanding of its own and third party instrument data and their usage in different applications. This includes data rescue, the detection and correction of artefacts and other long-term issues in instrument data time series, the estimation of uncertainties following metrological principles, the efficient production and delivery of climate data records as well as learning what it takes to bring data into usage, e.g., for deriving geophysical variables and for assimilation in global and regional reanalysis in the context of the Copernicus Climate Change Service. Results of the research projects, ongoing feedback from users and the EUMETSAT Member States, and upcoming new missions, such as the MTG and EPS-SG multi-satellite programmes and Copernicus missions, shape the evolution of EUMETSAT’s climate activities. The presentation reviews the scientific and technical achievements and lessons learnt and provides a prospect of future activities.
CALL: Virtual NASA JPL Center for Climate Sciences Summer School 2021
— Application period closed —
Each year, the Jet Propulsion Laboratory (JPL) Center for Climate Sciences (CCS), along with co-sponsors, the Keck Institute for Space Studies (KISS) at the California Institute of Technology (Caltech), and NASA’s Earth Science Division, assemble a new generation of climate scientists to engage with and learn from leading climate scientists from NASA, Caltech, and other universities and institutions. Applications are now being accepted through 30 April 2021 from science and engineering graduate students and postdocs to fill approximately 25 slots. The 2021 Summer School is currently planned as a virtual event from 9-13 August 2021, with the possibility of extending activities two days into the week prior or post.
Information about the school, as well as a link to apply can be found at https://climatesciences.jpl.nasa.gov/events/summer-school/about/. Students will participate in school activities via Webex and other meeting web platforms.

TALK: Satellite remote sensing for river hydrology
Dr. Elena Zakharov, Maynooth University of Ireland and Institute of Water Problem RAS Moscow Russia
11th Dec 2020, 11am.
Observations of river discharge have significantly reduced over the last 30 years. Although many national services continue observations of key rivers at key stations, the availability of these observations for the scientific community and for climate research is limited. Alternative methods of estimation and monitoring of river flow (modelling and satellite observations) have been rapidly developed to fill this gap. Hydrological modelling is a powerful tool giving insights at regional or basin scales; while satellites can provide worldwide observations. One of the widely used EO methods of discharge estimation is based on satellite altimetry. Altimetry provides reliable regular and weather-independent measurements of water height at a river cross-section. During the last two decades, several methods exploiting these measurements have been developed and tested worldwide on rivers of different size and morphology. Current presentation is dedicated to the review of the main methods and to assessment of the main factors affecting the accuracy of the EO discharge retrievals. Among the factors the satellite performance, the river scale, the character of the water regime and the channel morphology will be discussed.
TALK: How data science supports the global Tropospheric Ozone Assessment Report?
Colloquium by PD Dr. Martin G. Schultz, Jülich Supercomputing Centre, Forschungszentrum Jülich
30th Nov 2020, 5:00 pm.
The Tropospheric Ozone Assessment Report (TOAR) is an international activity involving more than 200 scientists, who summarize the state-of-research on tropospheric ozone, its global distribution and trends. Ozone is an important air pollutant with short and long-term impacts on human health, vegetation, and climate. The first phase of TOAR has recently been concluded. It produced 10 peer-reviewed articles in the open access journal Elementa – Science of the Anthropocene and one of the world’s largest collections of ground-level ozone measurements, which are freely available from the JSC web service https://join.fz-juelich.de. Over 30 independent follow-up publications have resulted from TOAR-I. Recently, TOAR began its second phase, aiming at an updated assessment in 2024. Again, this will be supported by JSC’s data infrastructure, but also through the development of new statistical methods and machine learning concepts, funded through the ERC Advanced Grant IntelliAQ. This talk will briefly summarize the main achievements of TOAR-I, introduce the enhanced TOAR data infrastructure under development at JSC and provide a glimpse into the machine learning activities of my Earth System Data Exploration group at JSC.
