Short summary

In a context of climate change, having sea level data all along the coast is essential. However, tide gauges yield pointwise observations, and satellite altimetry has limitations at the coast. We present a method that, learning from a years-long model output and using tide gauge observations only, is able to reconstruct sea level all along the coast. The accuracy of the reconstruction has been validated against independent observations and proven to be better than that of satellite altimetry.
