Snow depth mapping by lidar station Braemabuel
Listed in NASA Earthdata CMR
We developed a monitoring system using low-cost lidar (Livox Avia) and optical sensors, to measure snow depth variations in an avalanche release area at a high spatiotemporal scale (centimeter to low decimeter spatial resolution and hourly temporal resolution).
Description
A detailed description of the setup and a first data analysis is published in: [Ruttner-Jansen, P., Voordendag, A., Hartmann, T., Glaus, J., Wieser, A., & Bühler, Y. (2024).
Monitoring snow depth variations in an avalanche release area using low cost lidar and optical sensors. EGUsphere, 2024, 1-20.](egusphere.copernicus.org/preprints/2024/egusphere-2024-744/) This dataset contains hourly 3D lidar data of the snow surface at the test site Braemabuel in Davos, Switzerland from the winter season 2023-2024 (23.11.2023 - 14.04.2024). Braema1 is installed at 2191 m a.s.l. in the slope, looking up into the avalache release area, and Braema2 is installed at 2255 m a.s.l at the ridge, looking down.

Both scans together cover an area of about 15000 m². The data is in format ".las" and contains the points in XYZ [m], in the scanner own coordinate system - scalar fields: intensity, return number, timestamp, tag, label -- tag: binary code from Livox (see Livox Avia Manual) -- label: marking outliers (filtered by distance and SOR to get snow particles in the air)
