State pilots Airborne Snow Observatory project to test higher-resolution snow maps for Weber River operations
Summary
The Division of Water Resources described a multi-year Airborne Snow Observatory (ASO) project covering roughly 870 square miles of the Weber River watershed to test whether aircraft-based lidar and imaging spectrometry can improve runoff estimates and reservoir operations.
Scott McGettigan, water optimization section manager for the Utah Division of Water Resources, briefed the Utah Board of Water Resources on a new Airborne Snow Observatory (ASO) effort called “Wings Over Weber.”
McGettigan said the ASO approach uses airborne lidar and an imaging spectrometer to measure snow-depth and snow-water-equivalent at high spatial resolution across entire watersheds. “From 23,000 feet flying over, we can measure the snow depth to within about 2 and a half inches,” he said, describing the technology and…
