How Satellite Tech Imaged the Global Groundwater Crisis with James (Jay) Famiglietti

Jay Famiglietti, a leading hydrologist and former NASA scientist joins host Veena Srinivasan to talk about the groundbreaking GRACE satellite mission and its role in transforming global hydrology.

How can a satellite detect water buried deep underground? And what does this mean for how we understand and govern water resources across the world?

In this episode of the Water Data Podcast, Jay Famiglietti, a leading hydrologist and former NASA scientist joins host Veena Srinivasan to talk about the groundbreaking GRACE satellite mission and its role in transforming global hydrology.
GRACE measures tiny changes in Earth’s gravity to detect variations in water mass. This has enabled scientists to track groundwater depletion, glacial melt, and large-scale hydrological change across regions and over time.
