Numerical Simulations wave fields Davis Sea, WAVEWATCHIII, January 2020

This dataset contains numerical simulation results of the wave fields in the Davis Sea from end of December 2019 to start of February 2020. Hindcasts were obtained through the third-generation spectral wave model WAVEWATCH-III (hereafter WW3).


A high resolution Davis Sea regional grid (resolution 0.1 degree, 60-80E longitude, 70-60S latitude) was nested into global grid domain (resolution 0.5 degree, 80S-80N latitude). The global model is forced with 0.5 degree sea ice concentration and 10m-wind fields from ECMWF's ERA5 reanalysis. The Davis sea model is forced with 0.1 degree 10m-wind fields from ECMWF's archived forecasts, and high-resolution (3.125km) AMSR2 satellite data for sea ice concentration (Beitsch et al., 2013 updated). Ice-induced wave attenuation is parameterized following Sutherland et al. (2019, doi:10.1016/j.apor.2019.03.023) whilst the break-up of sea ice is parameterized as 'broken' or 'unbroken' based on the break-up parameter of Voermans et al.(2020, doi:10.5194/tc-14-4265-2020). The numerical simulations have been calibrated using the buoy-observations of Voermans (2022, dataset, doi:10.26179/cdmx-n995). Sensitivity of the simulations to sea ice properties was tested and all results are provided in the dataset.


The data tree:

* global: model outputs for the global domain

- ncfield: gridded wave and ice data for this domain in netCDF-4 format

- nests: binary data used by WW3 for boundary conditions for the Davis Sea grid

- restarts: binary data used by WW3 for restarting this domain

* davis_sea: model outputs for the Davis Sea domain

- ncfield: gridded wave and ice data for this domain in netCDF-4 format

- ncpoint: spectral wave data for a few points in the Davis Sea in netCDF-4 format

- nctrack: spectral wave data following the wave buoys of Voermans et al (2022) in the Davis Sea in netCDF-4 format

- restarts: binary data used by WW3 for restarting this domain

- IHOT: binary text field of broken and unbroken ice for restarting this domain



File naming convention (by example):

ww3.20200101_20200103_M3D_IHOT_H0P0325_A0P01_YY9P0_SS0P1_HH0P55.nc

* 20200101_20200103 identifies the datespan of the simulation in YYYYMMDD format

* A0P01 refers to the attenuation coefficient of the model (where P stands for 'point'), in this case, A=0.01

* YY is the Young's Modulus timed 10^9, here, Y-9.0e9 Pa

* SS is the ice strength 'sigma' times 10^6, here sigma=0.1e6

* HH is the ice thickness, here h=0.55 m

* H0P0325 is proportional to the epsilon calibration coefficient (H=0.5*ice_thickness*epsilon).

* M3D refers to the 3rd instantiation of the model

* IHOT refers to hot start using the ice breakup field from the previous week.


ww3.*_M3D_IHOT_H0P065_A0P05_YY6P0_SS0P55.nc is considered the baseline file (note, this simulation only covers the first two weeks of the study period).
