| Summary: | <!--!introduction!--> Reliable sea-level observations in coastal regions are needed to assess the impact of sea level on coastal communities and ecosystems. This paper evaluates the ability of in-situ and remote sensing instruments to monitor and help explain the mass component of sea level along the coast of Norway. The general agreement between three different GRACE mascon solutions and a combination of coastal satellite altimetry and hydrography gives us confidence to explore the mass component of sea level in coastal areas on intra-annual timescales. At first, the estimates reveal a large spatial-scale coherence of the sea-level mass component on the shelf, which agrees with Ekman theory. Then, they suggest a link between the mass component of sea level and the along-slope winds integrated along the eastern boundary of the North Atlantic, which agrees with the theory of poleward propagating coastal trapped waves. Our results give us confidence in the sea-level mass component from GRACE, satellite ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
