👉 The GMT Fluid, also known as the Greenwich Mean Fluid Level (GMFL), is a standardized measurement used primarily in hydrological and meteorological contexts to represent the average height of the Earth's oceans relative to a specific reference point, typically Greenwich Mean Sea Level (GMSL). This level is crucial for understanding and predicting sea-level changes, which are vital for climate research, coastal management, and flood risk assessment. The GMT Fluid is calculated using a combination of tide gauge data, satellite altimetry, and mathematical models that account for factors like gravitational variations and ocean currents. It serves as a consistent reference for comparing sea-level changes across different regions and time periods, facilitating global cooperation in addressing climate-related challenges.
