These are the hydrodynamic transient scenarios for the North Sea and the Northeast Atlantic for the period 1950-2006 (historical) and 2006-2100 (future). Atmospheric forcing originates from CMIP5 CORDEX EUR-11 regionalized scenarios (https://www.wdc-climate.de/ui/project?acronym=CORDEX_DDS-CMIP5_native-grid). The simulation has been performed with the hydrodynamic model TRIM-NP V2.5 in barotropic 2D mode. FES tides are included. Water level and current component fields are stored hourly. The model is set up on an equidistant Cartesian grid cascade with the center near Helgoland (7.88 E, 54.18 N). The coarsest grid with 12.8 km resolution covers the area from 20 W to 30 E and from 42 N to 65 N. Further 3 nested grids better resolve the North Sea (with 6.4km), southern North Sea (with 3.2km) and the German Bight (with 1.6km). Model data from grid 1 and grid 4 are available in this data bank. The file name of the data sets is composed as follows: trim_<spatial resolution>_<variable>_<global model>_<scenario>_<year>.nc spatial resolution: 12.8km (only ssh), 1.6km variable: ssh (sea_surface_height_above_sea_level), u_velocity (sea_water_x_velocity), v_velocity (sea_water_y_velocity) global model: mpi, had scenario: rcp85, rcp26 ,hist

These are the wind wave transient scenarios for the North Sea and Baltic Sea for the period 1961-2006 (historical) and 2006-2100 (future). Atmospheric forcing originates from CMIP5 CORDEX EUR-11 regionalized scenarios (https://www.wdc-climate.de/ui/project?acronym=CORDEX_DDS-CMIP5_native-grid). The simulation has been performed with the spectral wave model WAM Version 4.6.2. The model domain covers the area from approx 49.2° N to 66.6° N and 9.8° W to 31.6° E, with a spatial resolution of 0.044 degree latitude x 0.044 degree longitude (approx. 5 by 5 km) on a rotated grid with the coordinates of the rotated north pole 140°W E and 32° N. Integrated parameter derived from 2D spectra are available every hour. Lateral boundary conditions were obtained from corresponding coarse grid simulation covering most of the Northeast Atlantic driven by the same atmospheric forcing.

CO-MICC is a data portal for freshwater-related climate change risk assessment at multiple spatial scales. It is named after the research project during which it was developed, i.e. the CO-MICC (CO-development of Methods to utilize uncertain multi-model-based Information on freshwater-related hazards of Climate Change) project (2017-2021). The aim of CO-MICC is to support decision making in the public and private spheres dealing with future availability of freshwater resources. This climate service is operated and maintained by the International Centre for Water Resources and Global Change (ICWRGC), and more broadly by the German Federal Institute of Hydrology. The portal comprises data of over 80 indicators of freshwater-related hazards of climate change, which can be visualized in the form of global maps or interactive graphs. The indicators are dynamically calculated based on modelled annual and monthly gridded (0.5°) data sets of climate and hydrological variables. These data sets were computed by a multi-model ensemble comprising four Representative Concentration Pathways (RCPs), four General Circulation Models (GCMs), three Global Hydrological Models (GHMs) and two variants per hydrological model, which amounts to 96 ensemble members in total. They were provided by three European research modelling teams that are part of the ISIMIP consortium. The indicator data correspond to absolute or relative changes averaged over future 30-year periods, as compared to the reference period 1981-2010.
