Component contributions to extreme water levels. Panel (a) shows GTSM-ERA5 stations (in black) with highlighted “multi-POT” node locations marked in red and numbered to correspond with panel (c).

Study region with GTSM-ERA5 output locations marked as black circles and tide gauge locations marked as blue squares. Gray labels denote NOAA designated tide gauge station IDs. Information on tide gauges, including ID number, latitude, longitude, and the date when observations start, are listed in the table to the right of the map.
