Coupled climate-glacier modelling of the last glaciation in the Alps: modelling data

This dataset contains key distributed 2D variables resulting from the modelling of the Alpine Ice Field over the last glacial cycle from Jouvet and al. (2023, 10.1017/jog.2023.74), including basal surface topography, ice thickness, pressure-adjusted basal temperature, basal and surface ice flow speeds. The results are given on a raster grid in UTM system of coordinate with a spatial resolution of 2 km and a temporal resolution of 100 year. The data are compiled in netCDF. As explained in the paper, the model was designed to match LGM evidence. Modelled results related to intermediate states and to the Holocene must be interpreted with caution considering the relative coarse resolution (2 km). Small ice caps aside the main Alpine Icefield (except the Jura) were excluded.

本数据集包含Jouvet等人（2023年，DOI:10.1017/jog.2023.74）针对末次冰期旋回阿尔卑斯冰原（Alpine Ice Field）开展数值模拟所得到的关键分布式二维变量，包括冰床表面地形、冰厚、经压力校正的冰床温度、冰床与冰面冰流速度。所有结果以通用横轴墨卡托（Universal Transverse Mercator, UTM）坐标系下的栅格网格形式提供，空间分辨率为2千米，时间分辨率为100年。数据以netCDF格式编译存储。正如论文所述，本模型的设计目标是匹配末次盛冰期（Last Glacial Maximum, LGM）的观测证据。考虑到2千米的空间分辨率相对粗糙，针对冰期中间状态及全新世（Holocene）的模拟结果需谨慎解读。本数据集收录了侏罗山（Jura）地区的小型冰帽，主阿尔卑斯冰原外围的其余小型冰帽均未被纳入。
