NASA | Tracking Agricultural Water Use From Space

The video discusses the diverse water usage in U.S. agriculture and how satellite technology, specifically Landsat, helps monitor this usage. It explains the surface energy balance method to measure evapotranspiration (ET), which indicates water consumption. Monthly ET data aids resource managers in planning water budgets sustainably. The video highlights the importance of maintaining a balanced groundwater system and the development of the ET measurement system, now used by 15 states, to make informed water management decisions.

What challenges are associated with maintaining a balanced groundwater aquifer system?

In what ways has the metric system for measuring ET evolved since its development in the early 2000s?
