World Data Center for Climate

The mission of World Data Center for Climate (WDCC) is to provide central support for the German and European climate research community. The WDCC is member of the ISC's World Data System. Emphasis is on development and implementation of best practice methods for Earth System data management. Data for and from climate research are collected, stored and disseminated. The WDCC is restricted to data products. Cooperations exist with thematically corresponding data centres of, e.g., earth observation, meteorology, oceanography, paleo climate and environmental sciences. The services of WDCC are also available to external users at cost price. A special service for the direct integration of research data in scientific publications has been developed. The editorial process at WDCC ensures the quality of metadata and research data in collaboration with the data producers. A citation code and a digital identifier (DOI) are provided and registered together with citation information at the DOI registration agency DataCite.

Collaborative Research Centre Transregio 32 Database

In the framework of the Collaborative Research Centre/Transregio 32 ‘Patterns in Soil-Vegetation-Atmosphere Systems: Monitoring, Modelling, and Data Assimilation’ (CRC/TR32, www.tr32.de), funded by the German Research Foundation from 2007 to 2018, a RDM system was self-designed and implemented. The so-called CRC/TR32 project database (TR32DB, www.tr32db.de) is operating online since early 2008. The TR32DB handles all data including metadata, which are created by the involved project participants from several institutions (e.g. Universities of Cologne, Bonn, Aachen, and the Research Centre Jülich) and research fields (e.g. soil and plant sciences, hydrology, geography, geophysics, meteorology, remote sensing). The data is resulting from several field measurement campaigns, meteorological monitoring, remote sensing, laboratory studies and modelling approaches. Furthermore, outcomes of the scientists such as publications, conference contributions, PhD reports and corresponding images are collected in the TR32DB.

Horizont Europa, Rahmenprogramm für Forschung und Innovation (2021-2027), Flying ATM for Environment Climate

Flying alternative trajectories for the benefit of ClimateF4ECLIM's primary aim is to advance aCCFs by integrating weather forecasts and climate science to address uncertainties tied to CO2, contrails, ozone, methane, and water vapor climate effects. This involves evolving aCCFs to version 2.0, broadening their geographical scope (currently limited to the North Atlantic), considering diverse weather and seasonal patterns, and incorporating various climate metrics. These advancements will feed into a climate service for the aviation community. Additionally, F4ECLIM will explore aviation's potential to reduce its climate impact through the development of robust flight planning algorithms. These algorithms will identify eco-efficient aircraft trajectories, assessing the associated climate impact reduction and costs. Backtesting procedures will be employed to scrutinize trajectories and climate models, providing insights into model specifications. The project will culminate in recommendations and the introduction of key performance indicators (KPIs) to guide stakeholders in implementing eco-efficient trajectories, reducing uncertainties, and advancing understanding of the non-CO2 impact of aviation for a greener future.

HALO database

HALO-DB is the web platform of a data retrieval and long-term archive system. The system was established to hold and to manage a wide range of data based on observations of the HALO research aircraft and data which are related to HALO observations. HALO (High-Altitude and LOng-range aircraft) is the new German research aircraft (German Science Community (DFG)). The aircraft, a Gulfstream GV-550 Business-Jet, is strongly modified for the application as a research platform. HALO offers several advantages for scientific campaigns, such as its high range of more than 10000 km, a high maximum altitude of more than 15 km, as well as a relatively high payload.

Marine Data Portal

The Marine Data Portal is a product of the “Underway”- Data initiative of the German Marine Research Alliance (Deutsche Allianz Meeresforschung - DAM) and is supported by the marine science centers AWI, GEOMAR and Hereon of the Helmholtz Association. This initiative aims to improve and standardize the systematic data collection and data evaluation for expeditions with German research vessels and marine observation. It supports scientists in their data management duties and fosters (data) science through FAIR and open access to marine research data. AWI, GEOMAR and Hereon develop this marine data hub (Marehub) to build a decentralized data infrastructure for processing, long-term archiving and dissemination of marine observation and model data and data products. The Marine Data Portal provides user-friendly, centralized access to marine research data, reports and publications from a wide range of data repositories and libraries in the context of German marine research and its international collaboration. The Marine Data Portal is developed by scientists for scientists in order to facilitate Findability and Access of marine research data for Reuse. It supports machine-readable and data driven science. Please note that the quality of the data may vary depending on the purpose for which it was originally collected.

MOSES Data Discovery Portal

The MOSES Data Discovery Portal is the central component of the MOSES data management infrastructure. It holds the metadata of MOSES campaigns, sensors and data and enables high-performance data searches. In addition, it provides access to the decentral data repositories and infrastructures of the participating Helmholtz centers where MOSES data is stored.

IAGOS Data Centre

The IAGOS Data Centre manages and gives access to all the data produced within the project.

Untersuchung kombinierter Extremereignisse mit großen Ensembles von Klimamodellsimulationen

Klimafolgen werden typischerweise aus kombinierten Ereignissen (CEs) verursacht, also multivariate Kombinationen von klimatischen Treibern. Beispielsweise kann ein gleichzeitig heißer und trockener Sommer zu Vegetationsschäden führen, deren Auswirkungen oft die von Hitzewellen und Dürren für sich genommen übertreffen; gleichzeitige Waldbrände in mehreren europäischen Ländern können gemeinsam genutzte Einsatzmittel wie Löschflugzeuge überlasten und somit zu größeren Schäden führen. In den letzten Jahren ist aufgrund der Erkenntnis, dass eine univariate Perspektive auf Gefahren Klimarisiken möglicherweise stark unterschätzen und zu Fehlanpassungen führen kann, eine wachsende Zahl wissenschaftlicher Literatur zu CEs entstanden. Unser Verständnis von CEs, einschließlich der Quantifizierung, wie häufig sie auftreten und wie sie sich in Zukunft ändern werden, ist jedoch noch sehr begrenzt. Besonders die begrenzte Anzahl von Beobachtungen und routinemäßig verwendeten Klimamodellergebnissen macht die Forschung zu CEs sehr herausfordernd. Beispielsweise könnte man auf der Grundlage von einem kleinen Stichprobenumfang schlussfolgern, dass CEs an Orten selten sind, wo sie stattdessen sehr häufig sind. Das Hauptziel von ADVICE besteht darin, das volle Potenzial neuartiger Ensembles von Klimamodellen (SMILEs) auszuschöpfen, die Hunderte bis Tausende von Jahren an Daten des gegenwärtigen und zukünftigen Klimas liefern, um unser Verständnis von CEs zu erweitern. ADVICE baut auf früheren bahnbrechenden Beiträgen zur Erforschung von CEs durch den PI auf. Zwei Doktorand*innen werden gleichzeitig auftretendes Feuerwetter in europäischen Ländern und mehrjährige Dürren untersuchen, welche Ökosystemauswirkungen verstärken können, während ein Postdoc und der PI eine Reihe anderer CE-Typen untersuchen werden. ADVICE wird CE-Häufigkeiten und die damit verbundenen Unsicherheiten quantifizieren und so Informationen über Regionen mit erhöhtem CE-Risiko liefern. ADVICE wird Worst-Case-CEs untersuchen, die besonders extreme sozioökonomische Auswirkungen haben können. Die angemessene Kommunikation von Unsicherheiten in Prognosen ist unerlässlich, um irreführende Risikobewertungen zu vermeiden. Daher wird ADVICE verschiedene zukünftige Klimaentwicklungen abschätzen, einschließlich plausibler Worst-Case-Szenarien. Darüber hinaus werden Methoden zur Reduzierung von Unsicherheiten in CE-Projektionen untersucht. Insgesamt wird ADVICE die wichtigsten Vorteile von SMILEs für die Untersuchung von CEs sowie Informationen über die Fähigkeit von Klimamodellen bei der Darstellung von CEs herausarbeiten, was für Klimawissenschaftler*innen wichtig ist. Angesichts der Notwendigkeit einer multivariaten Perspektive in der Risikobewertung, werden die Ergebnisse von ADVICE zu verbesserten Klimarisikoabschätzungen beitragen, was letztendlich die Entwicklung der Anpassung an den Klimawandel unterstützen wird.

EURO-CORDEX 1989-2018 using TerrSysMP

Applying the Terrestrial Systems Modeling Platform, TerrSysMP, this dataset consists of the first simulated long-term (1989-2018), high-resolution (~12.5km) terrestrial system climatology over Europe, which comprises variables from groundwater across the land surface to the top of atmosphere (G2A). This data set constitutes a near-natural realization of the European terrestrial system, which cannot be obtained from observations, and can, thus, serve as a reference for global change simulations including human water use and climate change.
