Global Mean Sea Level Time Series

by
University of Colorado Sea Level Research Group

The University of Colorado Sea Level Research Group uses satellite radar altimeters to estimate global mean sea level.

These measurements are continuously monitored against a network of tide gauges. When seasonal variations are subtracted, they allow estimation of the global mean sea level rate. As new data, models and corrections become available, the Group continuously revises these estimates (about every two months) to improve their quality.
