CCI Sea Level

The main objective of the sea level CCI project is to produce and validate a Sea Level Essential Climate Variable (ECV) product. It represents the first phase of the ESA Climate Change Initiative program that aims at setting up in a second phase an "operational processing capacity of Earth Observation data"

ESA Climate Change Initiative

Climate change is arguably the greatest challenge facing mankind in the twenty-first century. Its importance has been recognised in recent reports from the IPCC and from UNFCCC, and the overwhelming economic consequences are set out in the Stern Report. Read more »

Along-track altimeter measurements - available to users

The Sea Level ECV products consist of monthly maps of sea level anomalies and associated mean sea level trends.

As part of the project's scientific activities, the Sea Level CCI project team have been able to provide the Climate Research Group with along-track altimeter measurements from several altimeter missions (TOPEX-Poseidon, ERS-1 & 2, Envisat, Jason-1 & 2) to assess the quality of the Sea Level ECV products using assimilation techniques.
