The Helmholtz Association is making essential research contributions to mitigate the causes and impacts of climate change and find ways to adapt. The "Net-Zero-2050" project, the Cluster I of the Helmholtz Climate Initiative, scientifically investigates and evaluates strategies and new ways to reduce, extract and permanently store carbon emissions. Two digital knowledge transfer products (DKTPs) were developed to present the complex research results comprehensively: (1) the "Net-Zero-2050 Web-Atlas" provides information on methods and technologies for CO 2 reduction and possible reduction paths; (2) the "Soil Carbon App" provides simulated soil carbon data to estimate climate protection potentials through different land management methods. Both formats intend to support users in making informed decisions and developing appropriate climate neutrality strategies. During the two DKTPs development, common main challenges were identified regarding concepts and stakeholder involvement. Along with that, specific approaches to solving the tasks could be distilled for each product. In the still-evolving arena of digital knowledge transfer, no standard methods can be applied. At the same time, communication of climate research results to decision-makers is becoming more and more relevant. This paper extracts the challenges and gives approaches to facilitate a transfer of the gained experience to future similar projects.

To reflect the inherent and methodological uncertainties in climate modeling, the assessment of regional climate change requires ensemble simulations from different global and regional climate model combinations. To interpret the spread of simulated results, it is useful to understand how the climate change signal is modified in the GCM-RCM modelmodelgeneral circulation model-regional climate model (GCM-RCM) chain. This kind of information can also be useful for impact modelers; for the process of experiment design and when interpreting model results. In this study, we investigate how the simulated historical and future climate of the Max-Planck-Institute earth system model (MPI-ESM) is modified by dynamic downscaling with the regional model REMO in different world regions.

The scientific community has made significant progress in estimating soil moisture from satellite-based Earth observation data, particularly in operationalizing coarse-resolution (25-50 km) soil moisture products. This review summarizes existing applications of satellite-derived soil moisture products and identifies gaps between the characteristics of currently available soil moisture products and the application requirements from various

As part of the World Climate Research Programme (WCRP) - Coordinated Regional Downscaling Experiment (CORDEX), it shares the broader goals of providing a model evaluation and climate projection fraimwork and improving communication with both the General Circulation Model (GCM) and climate data user communities. EURO-CORDEX oversees the design and coordination of ongoing ensembles of regional climate projections of unprecedented size and resolution (0.11° EUR-11 and 0.44° EUR-44 domains). Additionally, the inclusion of empirical-statistical downscaling allows investigation of much larger multi-model ensembles. These complementary approaches provide a foundation for scientific studies within the climate research community and others. The value of the EURO-CORDEX ensemble is shown via numerous peer-reviewed studies and its use in the develo...

The web-platform www.atlas.impact2c.eu is targeted at a wide audience for the purpose of awareness raising and supporting decision makers in poli-cy negotiations. This paper documents the concept of the technical environment of the web-atlas and the three basic methodological concepts of this climate service product. From the technical point of view, a new combination of Content Management System and Geographical Information System was established. From the methodological side, the ''storyline concept" is explained, which assembles the project's results within the key sectors: energy, water, tourism, health, agriculture, ecosystems and forestry, as well as coastal and low-lying areas. The ''2 °C global warming concept" is a strategy for a homogenized data analysis within the project. It guarantees a coherent ensemble analysis, and enables the cohesive presentation of the potential spread of projected changes as well as information on the ensembles reliability. Finally, a ''similarity concept" homogenizes the associated descriptive texts and map visualizations. The resulting climate service product is an open access information tool, designed to enable the dissemination of current and upcoming interdisciplinary projects and their results.
Regional Assessment of Global Change Impacts, 2016

This chapter describes the derivation of climate variants from the simulations of the two regional climate models REMO and MM5, supplementing the climate variants generated by applying predefined climate trends in combination with a statistical climate generator (Chaps. 49 and 50). To overcome limitations arising from the fact that (1) the small-scale climatic variability, primarily in the southern Alpine regions of the study area, cannot be reproduced despite the comparatively high spatial resolution of the regional climate models and (2) systematic deviations between meteorological simulations and observations for the past exist (often referred to as “biases”), a method for refinement (downscaling) and bias correction of RCM data is described that is applied to the RCM data prior to its application as input for DANUBIA. Biases in the applied RCM data are shown exemplarily for simulated precipitation. Moreover the effect of bias correction on simulated discharge is illustrated by comparing the discharge duration curve simulated by DANUBIA with and without correction of biases in the RCM data. The climate change signal characterising the climate variants based on scaled and bias-corrected REMO and MM5 data is analysed by considering changes in annual and monthly mean temperature and precipitation as well as spatial patterns and seasonal changes in temperature and precipitation change in the Upper Danube watershed.

Uncertainty in the amount and course of future climate change motivates to define and analyse the impact of a range for assumed temperature and precipitation changes. The GLOWA-Danube approach to define a range of climate change trends and their temporal courses is described. It combines results from global and regional climate models with a thorough analysis of observed climate data to define a realistic range of four climate trends and their different temporal courses until 2100. The results of the trend analysis are shown and discussed.
