Project: coastDat-3 - CoastDat-3 (http://www.coastdat.de/about_us/index.php) comprises a compilation of consistent hindcasts obtained from numerical models. The atmospheric part of the dataset is simulated by using the COSMO in CLimate Mode version 5 (http://www.clm-community.eu) with different boundary conditions. The objective is to provide a consistent meteo-marine data set. Summary: This datasets contains simulation output for the global hydrological models HydroPy and MPI-HM. Both used meteorological forcing from the GSWP3 dataset for the period 1979-2014 and a 50 years spinup period. The analysis of this simulations is published at https://doi.org/10.5194/gmd-2021-53 .
