Monthly-sampled waterline data (North American West Coast, 1997-2022)

Satellite-derived waterline data (netcdf format, .nc) along the North American West Coast, for each transect. Two files for 2 datasets, 2000-2022 and 1997-2022 (refer to Methods in Graffin et al. (2025)). - 'shoreline' : Monthly-sampled waterline positions (demeaned). - 'fit' : Long-term trends of waterline change. - 'cycle' : Seasonal cycles of waterline change. - 'anom' : Anomalies of waterline change. - 'slope' : Upper-intertidal beach slopes (estimated using the methodology from Vos et al. (2020)). - 'lon' : Transect longitude coordinates. - 'lat' : Transect latitude coordinates. The files also contain wave, wind and sea-level data used in the study. -------------------------------------------------------------------------------------------------------------------------------------- Example of code to use the data : import xarray as xr data = xr.open_dataset('yourpath/file.nc') shorelines = data.shoreline lon,lat = data.lon,data.lat significant_wave_height = data.hs sea_level_anom = data.sla
