NASA Follows Changing Freshwater from Space

The video explores Earth's water distribution, highlighting that only 3% is fresh and crucial for life. NASA satellites play a vital role in monitoring water resources, providing data on droughts, floods, and water quality. The GRACE mission tracks aquifer levels, while other satellites observe soil moisture and vegetation growth. Monitoring lakes and rivers helps manage water quality, especially concerning algae blooms. Snowpack changes due to climate warming affect water availability. Understanding these dynamics aids in better water management globally.
