Sea Level Change

Since 1993, the TOPEX, Jason 1 and 2 as well as ERS1 and ENVISAT satellite radar altimeters have provided uninterrupted accurate estimates of global mean sea level. These measurements are continuously monitored for quality and calibrated against a network of tide gauges. These data allow estimation of the global mean sea level rate taking into account oceans up to 82N. As the time-series are extended with new data and better models and corrections become available these will be posted on altimetry.dk.
