Annual glacier surface flow velocity product from Sentinel-2 data for the European Alps

Glacier ice flow velocity is an important variable to document the past and current status of the glacier worldwide. The aim of the ESA AlpGlacier project is to create innovative products for glaciers and their environments from remote sensing data for the European Alps mountain range. The data set proposed here includes maps of annual glacier surface flow velocities for the period 2015-2021, created from Sentinel-2 optical data with the work-flow presented in Mouginot et al., 2023. It can be used for the monitoring of glacier dynamics or for hazards detection associated to glaciers destabilization, as well as an input of models calibration and validation. These products are distributed in both netCDF and GeoTiff formats, georeferenced under the UTM-32N projection.

冰川冰流速是记录全球冰川过去与当前状态的重要变量。欧洲空间局（European Space Agency, ESA）AlpGlacier项目旨在基于遥感数据，为欧洲阿尔卑斯山脉的冰川及其周边环境研发创新型产品。本数据集涵盖2015-2021年的冰川表面年流速分布图，该数据基于哨兵二号（Sentinel-2）光学影像，采用Mouginot等人2023年提出的工作流生成。该数据集可用于冰川动力学监测、冰川失稳相关灾害识别，亦可作为模型校准与验证的输入数据。上述产品以netCDF与GeoTiff两种格式分发，采用UTM-32N投影进行地理配准。
