NASA tech lets scientists see snow water through the trees
NASA scientists are testing a technology that could more accurately measure water stored in snow as seen from a satellite in orbit. Melting snow provides much of the water that the western United States depend on for agriculture and power. But warming winters due to climate change led to decreased seasonal snowpacks high up in the Rockies and Sierra Nevada mountains. That in turn affects the volume of water that travels downriver to irrigate crops and turn hydroelectric turbines.
