Altim

Validating recently-developed twenty-first century regional sea level projections using satellite observations

Sea level rise is one of the basic consequences of the increase in global mean temperature. Oceans expand and change their circulations and glaciers and ice sheets melt. The increase in the sea-level is not uniformly distributed and varies regionally. The main aim of Altim is to analyze the sea-level trend and the natural variability around this trend for the North Sea basin, and to examine the different contributions. One goal of Altim is to assess which of the recently-developed scenarios for regional sea level change is most likely ongoing.

Correlation between observed sea-level variability as obtained with satellite altimetry for the period 1993-2014, and modelled sea-level variability. The model is a statistical model that includes information from a.o. wind, temperature, pressure. Only co
