To improve flood preparedness, the Copernicus Early Warning Service – Hydrological forecasting (CEMS-Floods) monitors and forecasts the hydrological status at the European and global scales. This allows support national flood forecasting authorities by providing complementary and added value information. The CEMS-Floods Analytics and Dissemination Centre analyzes the forecasts daily, requests pre-tasking for rapid impact assessment, disseminates information to partners and the Emergency Response Coordination Centre. In addition, the centre organizes the annual partner meetings, provides trainings webinars and videos, collects feedback from partners, as well as manages the communication tool. Finally, the centre is compiling various reports during the year to justify the high-quality service provided to the partners and European Commission, and also to share the deep understanding and knowledge on extreme flood events and how these events are handled by early warning services. The investigations and service process understanding provides feedback for the future evolution of the CEMS-Floods awareness services.

The main objective of CLINT is the development of an Artificial Intelligence framework composed of Machine Learning techniques and algorithms to process big climate datasets for improving Climate Science in the detection, causation, and attribution of Extreme Events (EEs), namely tropical cyclones, heatwaves and warm nights, droughts, and floods. The CLINT AI framework will also cover the quantification of the EE impacts on a variety of socio-economic sectors under historical, forecasted, and projected climate conditions, and across different spatial scales (from European to local), ultimately developing innovative and sectorial AI-enhanced Climate Services. Finally, these services will be operationalized into Web Processing Services, according to the most advanced open data and software standards by Climate Services Information Systems, and into a Demonstrator to facilitate the uptake of project results by public and private entities for research and Climate Services development.

Purpose: The project DIRT-X addresses the question of how the changing climate and socioeconomic conditions influence water reservoirs and the services they provide to different economic sectors through integration of existing climate services, projections of socioeconomic conditions (SSPs), impact models, and close cooperation with stakeholders from the relevant sectors. By combining local scale analyses with regional and global scale analyses of hydrological processes and relevant socio-economic developments we achieve better understanding and quantification of the impacts and uncertainties inherent in climate impact assessments, especially as they relate to scale and resolution. The integration of hydrological process modelling with economic models assessing water stress, cross-sectoral conflicts, and energy system enables investigation into the how hydrologic impacts are best translated into economic consequences and what are the implications of climate impacts within these systems.

Purpose: A new generation of Regional Climate Models (CPRCM) with very high spatial resolution (<5 km) is under development. With this resolution, both atmospheric processes and geographical conditions can be described in a much more realistic way than in earlier, more low-resolution models. From a hydrological point of view, it is particularly interesting that convective processes in the atmosphere are explicitly described in CPRCMs, which means that rainfall and rainfall consequences can be studied more realistically. One problem, however, is that CPRCMs require extremely large computing capacity and therefore only a limited number of simulations can be done, for a selected region, for selected time periods. A key question then becomes which of all global scenarios should be selected for downscaling with a CPRCM, to get a "mini-ensemble" that best describes the uncertainty and is as useful as possible for climate adaptation. In EDUCAS, in dialogue with end users, we will assess the added value of CPRCM simulations for different hydrology applications, air environment and oceanography, and use this information to make an optimal selection of global scenarios. The hydrological analysis will focus on rainfall, its properties on different scales in time and space, in today's and future climate.

Purpose: The aim of the project is to investigate multiple hydrometeorological extremes and compound events that might occur simultaneously, cascadingly or cumulatively and can cause severe impacts. In Sweden, these events arise mainly from snowmelt and peak river flow, heavy and persistent large-scale rainfall, small scale cloudbursts, and coastal surges. Together with the Oceanography Unit and the Rossby Centre of SMHI, we assess risk hot-spots and related physical processes for water-related multiple extremes and compound events in Sweden. The overall aim of the project is to examine how exposure and vulnerability to multiple water-related hazards lead to different types of cumulative and interactive impacts on Critical Societal Services (CSSs) and Infrastructure and populations. The project wants to contribute to the Swedish Disaster Risk Reduction (DRR) policies and practices with a specific focus on the management of multiple water hazards and potential mitigation and adaptation strategies.
