This sensor was installed just subtidally in the mudflats about a kilometer offshore of the eastern shore of south San Francisco Bay (see point BMV in Fig. 1). Timeseries comparisons from both seasons are visible in Fig. 2 in the data release. In the summer, the model recreated the daily sea breeze-driven wave field. For the summer season, RMSE of simulated significant wave heights was 0.08 m with a modeled seasonal-mean significant wave height of 0.22 m and bias of -0.031. In the winter, RMSE of simulated significant wave heights was 0.07 m with a modeled seasonal-mean significant wave height of 0.10 m and a bias of -0.035 m. Despite proportionally high RMSE values to modal wave heights, there was decent agreement in the distribution of wave heights across the seasons (Fig. 3 in the data release), which are ultimately critical towards average and cumulative wave power metrics relevant for marsh-edge erosion, which this model was developed for. Logical_Consistency_Report: Wave height data fall within expected ranges, with only a few specific exceptions at moments when water depth at some model locations becomes extremely small or zero, leading to erroneous wave metrics; these data should be neglected in analyses. Other than these moments, mean wave period (Tm) data generally fall within expected ranges. Peak wave period (Tp) values should be interpreted conservatively as the value can change rapidly and be nonsensical in periods with very low wave energy. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

The model application included two domains that were 1-way coupled. The coarse overall model domain (wsfb_g1.grd) included the coastal ocean across the entire San Francisco Sacramento/San Joaquin Bay-Delta region was forced along the oceanic boundaries with measured time-varying, spatially uniform wave parameters derived from CDIP station 029 (Point Reyes). The nested detailed model (wsfb_g2.grd) covered south San Francisco Bay and was forced with simulated wind data from the High Resolution Rapid Refresh (HRRR) atmospheric model produced by NOAA with a spatial resolution of 3 km and temporal resolution of 1 hour. Water level data provided from NOAA station 9414523 (Redwood City, California) were used throughout the model domains to simulate tidal variations. Bathymetry data were compiled from Fregoso and others, 2017 and Fregoso and others, 2020. Water density was fixed at 1023 kg/m3 to reflect brackish conditions; a Collins bottom-friction formulation was used with coefficient 0.02; Van der Westhuysen whitecapping was used for better performance in wind-dominated systems. The model inputs were split into 4 time intervals (summer, fall, winter, spring) and run sequentially to simulate approximately 1 year.
