Sierra Nevada Snow Pack & Snow Melt

The video explores the Sierra Nevada mountain range's role in California's water supply, highlighting the impact of changing precipitation patterns due to climate change. Researchers, including Martha Conklin and Tom Harmon, study snowpack and snowmelt to improve water management. The Southern Sierra Critical Zone Observatory collects data to understand snowpack dynamics, using wireless sensors and flux towers. This research aids in predicting water availability and helps water managers allocate resources effectively.
