Wave model results of the central Beaufort Sea coast, Alaska

September 29, 2021

A three-level SWAN (version 41.31) nesting grid has been developed for the central Beaufort Sea coast to simulate waves over the hindcast period 1979 - 2019. The model includes the implementations of sea ice by Rogers (2019) and includes both 1) a dissipation source term and 2) a scaling of wind input source as functions by sea ice. The bathymetric dataset used for the model is the International Bathymetric Chart of the Arctic Ocean (IBCAO Version 4.0 Compilation Group, 2020).

Meteorological forcing conditions (wind and sea ice concentrations) along the model boundary were based on ERA5 reanalysis (Hersbach and others, 2020). ERA5 provides hourly estimates of a large number of atmospheric, land, and oceanic climate variables at 30-kilometer resolution. Here we provide the grids and the bathymetries needed to run the model as introduced in Nederhoff and others (2021), as well as summary statistics for wind and wave parameters and for sea ice coverage. In addition, time series files for the years 1979-2019 with wave, wind and ice parameters output files are provided for the area.
