**Summary**: Some plants are simply better at making use of their water supply than others. More efficient plants can capture more carbon with less water, which has implications for carbon sequestration and ultimately for climate change modeling. In other words, the more we understand about water use efficiency, the more reliable our climate change models can be. And the only way to measure efficiency at the global scale is from space. On this episode of Eyes on Earth, we hear from a scientist who studied global water use using a sensor called ECOSTRESS, whose data are housed at the USGS EROS Center, in NASA’s Land Processes Distributed Active Archive Center (LP DAAC).

**Guests:**Savannah Cooley, Applied Science Systems Engineer, NASA Jet Propulsion Laboratory

**Host:** John Hult

**Producer:** John Hult

**Release date:** May 2, 2022

**More on ECOSTRESS and Global Water Use:**
                                - Convergence in water use efficiency within plant functional types across contrasting climates
                                - Eyes on Earth Episode 65 – Rapid Fire Mapping with Remote Sensing
                                - Eyes on Earth Episode 63 - ECOSTRESS and Post-Fire Recovery
                                - Eyes on Earth Episode 70 - ECOSTRESS and Aquatic Ecosystems
