Web19 de jun. de 2024 · The biggest disadvantage of satellite altimetry is “the contamination of the radar signal near the coast when the reflection of the radar pulse is partly due to the ocean surface and partly to land” (Gomis, Monserat et al., 2012). As a consequence, the standard altimetry data is unreliable at distances shorter than 40 km from the coast.
