Overviewextentflowseasonalitysurface water
A virtual time machine that maps the location and temporal distribution of water surfaces at the global scale over the past 3.5 decades, and provides statistics on their extent and change to support better informed water-management decision-making. Data is provided on surface water occurrence, change in occurrence, surface water seasonality, surface water recurrence, transitions in surface water class (permanent or seasonal) and maximum extent over the time period of the data.
