BYU is updating its Snow-Inspector Tethys app. The Snow-Inspector app visualizes the percentage of snow in a given area over a period of time. The update will include the snow mass and the snow-water equivalent in each area. The updated Snow-Inspector app will also explain why any data is missing. The Snow-inspector is designed to observe changes of snow coverage over time. This app allows users to accurately predict the amount of snow will melt and the amount of water in the melted snow.
