Abstract:
At Neumayer-Station in Antarctica snow height is permanently monitored with a laser distance meter. The instrument measures continuously since 2013-01-01 and is located in the vicinity of the Air Chemical Observatory Neumayer. By design, the sample area of the surface is on the order of a few millimetre in diameter. Long-term trends of the measured snow height are strongly correlated with accumulation on the ice shelf at a horizontal scale of several kilometres. Short-term trends reflect dynamic changes of the surface and can be used to deduce information on surface roughness.

Comment:
The instrument was dysfunctional from 2022-10-16 until 2022-12-19 due to defect of a communication device. On 2022-12-22 the sensor was replaced with a succeeding model (Lufft, SHM 31).
