北极黄河站2016年Austre Lovénbree和Pedersenbreen冰川运动GPS观测数据

在北极黄河站附近的Ａ冰川和Ｐ冰川上钻孔埋设监测标杆，用于开展冰川GPS和物质平衡观测。GPS观测所用设备为Leica GX1230型GPS接收机，配备Leica AX1202型天线。冰川运动和末端位置观测是以北极黄河站GPS卫星跟踪站作为差分主站，对两条冰川的全部标杆以及Austre Lovénbree冰川末端位置控制点进行高精度GPS测量，通过后处理差分计算，得到各观测点相对于黄河站的精确坐标值。两条冰川上每个观测点的测量时间在1小时以上，部分点位进行了两次甚至三次测量，测量精度达到了水平方向优于1 cm、高程方向优于2 cm的水平；冰川末端位置控制点的测量时间约为20分钟，测量精度达到厘米级，完全满足冰川研究工作的需要。

数据处理采用北极黄河站GPS跟踪站作为主站进行后处理差分，黄河站的GPS跟踪站坐标定为CNYR（78°55‘21.36000"N，11°56‘07.81000"E，H＝46.116m。

本数据为2016年黄河站冰川运动GPS观测数据，采用word格式存储，包括观测点名称、观测时间、经度、经度误差、纬度、纬度误差、高度和高度误差等信息。数据表格中，冰川监测点的头两位是点名，*new表示旧的标杆已经倒伏不能准确定位，因此新埋设标杆，不能与前面的位置数据比对；*P表示原来标杆倒伏，测量位置是倒伏现场的标杆根部，即可能的点位。

Drilling and embedding monitoring poles on Glacier A and Glacier P near the Arctic Yellow River Station for glacier GPS and mass balance monitoring. The GPS monitoring equipment used is the Leica GX1230 GPS receiver, equipped with a Leica AX1202 antenna. For glacier movement and terminus position monitoring, high-precision GPS measurements were conducted on all poles of the two glaciers and the terminus control points of Austre Lovénbree Glacier, using the GPS satellite tracking station at the Arctic Yellow River Station as the differential reference station. Precise coordinates of each monitoring point relative to the Yellow River Station were obtained via post-processed differential calculation.
The measurement duration for each monitoring point on the two glaciers exceeded 1 hour, with some points measured twice or even three times. The measurement accuracy achieved better than 1 cm in the horizontal direction and better than 2 cm in the elevation direction; the measurement duration for the terminus control points was approximately 20 minutes, with centimeter-level accuracy, which fully meets the requirements of glacier research.
For data processing, post-processed differential calculation was carried out using the GPS tracking station at the Arctic Yellow River Station as the reference station. The coordinates of the Yellow River Station GPS tracking station are designated as CNYR (78°55'21.36000"N, 11°56'07.81000"E, H=46.116 m).
This dataset consists of 2016 glacier movement GPS monitoring data collected at the Yellow River Station, stored in Word format. It includes information such as monitoring point name, observation time, longitude, longitude error, latitude, latitude error, elevation, and elevation error.
In the data table, the first two characters of each glacier monitoring point are the point name. The marker *new indicates that the original pole had toppled over and could not be accurately positioned, so a new pole was installed, and its position data cannot be compared with the previous records; the marker *P indicates that the original pole had toppled over, and the measurement was conducted at the base of the toppled pole, i.e., the approximate original position.
