Short summary
This paper evaluates the capability of satellite altimetry to monitor coastally trapped waves in light of the latest advancements in daily gridded sea level data, including new interpolation schemes, an increased number of missions in orbit, and the incorporation of wide-swath altimetry measurements. The eastern Australian coast serves as a testbed, with validation provided by tide gauges and model data.
