TodaiWW3-ArCS hindcast simulation during the MR20 drifting buoy observations: gridded model output.

This is a hindcast simulation during MR20 drifting buoy observation using TodaiWW3-ArCS. This dataset is related to the "MR20-05C drifting wave buoy observation in the freezing marginal ice zone" dataset (ADS metadata ID A20241112-006 : MR20-05C drifting wave buoy observation in the freezing marginal ice zone). Grid model output for wave heights, periods, and directions are provided. The model setup is the same as the experimental TodaiWW3-ArCS wave forecast model to support R/V Mirai Arctic Ocean expedition (ADS metadata ID: A20220927-002 : Experimental wave forecast to support R/V Mirai Arctic Ocean expedition in 2020). The model was forced with the ERA5 10m wind field while the lateral boundary was imposed using 0--23 hr lead time RIOPS ice concentration and thickness forecast produced by the Environment and Climate Change Canada (ECCC). The hindcast model was used to investigate the wave event measured by the Spotter drifting wave buoys on 16 and 17 Oct in the marginal ice zone. The event was studied because southwesterly waves were measured when the local and dominant winds in the adjacent ice-free water were blowing from southeast.
