Snow Depth Lidar Point Clouds from Davos, Switzerland, Winter 2023-2024

Davos, Switzerland hosts hourly 3D lidar scans of snow surfaces from two stations (Braema1 and Braema2) covering approximately 15000 m². The data spans the winter season from November 23, 2023 to April 14, 2024. The dataset is associated with a research publication from 2024.

Use Cases

• Modeling avalanche risk based on hourly snow depth variations
• Analyzing snow surface evolution over time based on high spatiotemporal resolution
• Developing snow particle filtering algorithms based on labeled outlier data
• Calibrating low-cost lidar systems for environmental monitoring based on the described setup

Strengths

• Hourly temporal resolution provides fine-grained time-series data
• Centimeter to decimeter spatial resolution captures detailed surface changes
• Covers an area of approximately 15000 m² from two complementary scanner positions

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic/temporal bias inherent to nasa_earthdata
