coastDat historical severe storm tides in the German Bight

The hydrodynamic model Trim-NP (2.6) was used to get an impression of the spatial distribution of water levels at the coast during historical severe storm tides. For these events, the atmospheric reanalysis products from the Twentieth Century Reanalysis project (20CR), (Compo et al., 2011; Slivinski et al., 2019) and from the ECMWF (ERA5 and UERRA-HARMONIE) (Hersbach et al., 2018, Copernicus Climate Change Service, 2019) are used to force the model. Additionally, the German weather service (DWD) developed reanalysis data for storm surge events for the project OptempS-MohoWif (Kristandt et al., 2014). These reanalysis data are calculated three days before the event and two days after. Based on the comparison between tide gauge observations and model output, we can estimate, the skill of the reanalyses in simulating severe storms. All model runs are forced by finite element solutions tidal atlases FES2004 at the lateral boundaries (Lyard et al., 2006). Further information about the reanalyses:

The file name of the data sets is composed as follows.

trim_<grid>.<variable>.<forcing>_<year>_<run>.nc

grid: 2 ( 6.4 km resolution) and 4 (1.6km resolution)

variables: u10(x_wind), v10(y_wind) und e(sea_surface_height_above_sea_level)

forcing: 20CR versions(v2c und v3) and (UERRA, ERA5) for ECMWF and OptemptS

Year: 1825, 1949, 1953, 1962, 1967, 1976, 1999, 2013

run: only used for the 20CR project with 56 (v2c) and 80 (v3) ensemble members

Depending on whether the forcing data was available, data are generated.
