High resolved snow height measurements at Neumayer Station, Antarctica, 2023

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.

位于南极洲的诺伊迈尔站（Neumayer-Station）采用激光测距仪（laser distance meter）对雪面高度开展持续性监测。该设备自2013年1月1日起持续运行，部署于航空化学观测站诺伊迈尔（Air Chemical Observatory Neumayer）周边区域。按照设计方案，其地表采样区域的直径仅为数毫米量级。所测得的雪面高度长期变化趋势，与水平尺度为数公里的冰架区域积雪累积量呈显著相关关系；而短期变化趋势则反映了地表的动态变化过程，可用于反演地表粗糙度相关信息。
