以加拿大生产的EKKO-Pro型探地雷达,并采用50和100MHz两种天线,对冰川厚度进行雷达测量。在测量之前,首先利用皮尺和不同频率天线,检测了冰川冰中雷达波的传播速度,并将其应用到雷达主机的厚度计算中,获得最高精度级别的冰川厚度。
用探地雷达测量前,先进行雷达波速在冰川冰内传播速度的测量,并对探地雷达相关参数进行修改,确保获取对应冰川最精确的厚度数据。

论文题目:Extracting the spatio-temporal evolution and geographical featuresof shrinking Mountain glacier group during 1989–2017
论文摘要:The climate-induced spatio-temporal evolutionary characteristics of glaciers have a strong response in understanding the surface earth system processes, including hydrology, ecology, and topography. With use of multispectral remote sensing, this study explores the longtime glacier shrinkage evolution and their geographical features of Mountain glaciers (i.e. Gongga Mountain glacier group), ineastern Qinghai-Tibetan Plateau, China. We used a band ratio and decision-tree classification mixed method to automatically delineate Gongga Mountain glaciers shrinking nature. Based on the multispectral Landsat images over nearly 30 years, the long-time spatiotemporal shrinkage evolution of Gongga Mountain glaciers was extracted, in which the glacier shrinkage area changes are consistent with the results from previous works. This study analyzed the nature of shrinking glaciers with topographic derivatives (i.e., different glacier scale, altitude, slope gradient, and slope direction). We noticed that the characteristic of shirking glaciers is associated with the topographic variables. The maximum shrinkage was concentrated at altitudes of 5000–5500 m, and a slope angle of 30 in the south irection. Findings shed light that glaciers in our study area are correlated with temperature changes and precipitation with a correlation
coefficient of 0.97 and 0.35, respectively, suggesting that the decreasing glaciers are highly correlated with the temperature increase. This study implies the usefulness of remote sensing in understanding the long-time ecological environment change and helping manage the potential glacial disasters in eastern Qinghai-Tibet Plateau.

I am the maintainer of GlaThiDa – the Glacier Thickness Database – described in this paper (https://doi.org/10.5194/essd-12-3039-202), developed on GitLab (https://gitlab.com/wgms/glathida), and released on the GTN-G website (https://www.gtn-g.ch/data_catalogue_glathida/). I hope to include your ice thickness datasets to GlaThiDa for the benefit of the community. The database lists the original investigators, data sources, and literature references.
