Sea Surface Height Time Series for the Western and Eastern U.S. Gulf Coasts over 1900–2100

Dataset: ssh_reconstruction_GulfCoast_rcp85_1900_2100.nc Description: This dataset contains sea surface height (SSH) time series for the Western and Eastern U.S. Gulf Coast regions over 1900–2100. The simulated SSH time series were obtained using the High-Resolution Community Earth System Model (HR-CESM) as part of the iHESP project (Chang et al., 2020; Zhang et al., 2020). The reconstructed SSH time series were obtained using the ECCO adjoint convolution method (Delman et al., 2026; Wang et al., 2026). The dataset includes: - HR-CESM simulated SSH - Total reconstructed SSH - SSH reconstructions associated with: * surface heat flux * freshwater flux * zonal wind stress * meridional wind stress Region Definitions: Western Gulf Coast: Average over model grid cells nearest to land grid cells west of the Mississippi River. Eastern Gulf Coast: Average over model grid cells nearest to land grid cells east of the Mississippi River.
