GLOSS – Global Sea Level Observing System

The Global Sea Level Observing System (GLOSS) is an international program that monitors sea level changes using a network of high-precision tide gauges around the world. It provides critical data for climate research, oceanography, and coastal management. GLOSS supports satellite altimetry calibration and contributes to understanding long-term sea level trends and variability.
