Snow height and air temperature on sea ice from Snow Buoy measurements

The resulting time series describes the evolution of snow height as a function of place and time in sample intervals of 1 hour. The Snow Buoy consists of four independent sonar measurements representing the area (approx. 10 m²) around the buoy.

In addition to snow height and air temperature, geographic position (GPS), barometric pressure, and an internal ice temperature were measured. Negative values of snow height occur if surface ablation continues into the sea ice. Thus, all snow height measurements describe the surface elevation relative to the original snow-ice interface.
