Greenland GPS Network (GNET) 2007-08-11 to 2018-07-31

The GNET (Greenland GPS Network) dataset contains GPS data from 41 continuously observing GPS stations installed in bedrock near the Greenland coast. The network was installed primarily to measure how bedrock is responding to ice mass change, including spatial shifts in the position of the centers of ice loss and accelerations in mass change rates. The network senses seasonal oscillations in the vertical position of the earth's crust, as well as longer term trends. Seasonal oscillations are due to loads placed on the solid earth by both the atmosphere and the ice sheet. GNET helps address a problem of great interest and societal importance: the trajectory and magnitude of Greenland ice mass balance.

GNET（Greenland GPS Network，格陵兰GPS监测网）数据集包含安装于格陵兰海岸附近基岩中的41台连续运行GPS监测站的GPS观测数据。该监测网的布设初衷主要为测量基岩对冰量变化的响应情况，涵盖冰体流失中心的空间位移以及冰量变化速率的加速现象。该监测网可捕捉地壳垂直位置的季节性振荡与长期趋势性变化，此类季节性振荡源于大气层与冰盖对固态地球施加的负载。GNET有助于解决一项兼具重大科研价值与社会意义的课题：格陵兰冰量平衡的变化轨迹与规模。
