Deflation Patch Characteristics

Landscape position data for soil deflation landforms in West Greenland. Field measurements include scarp length, scarp height, and patch size. Elevation, aspect, slope, and distance to the Greenland Ice Sheet were calculated with imagery acquired from the Polar Geospatial Center. We calculated the patch expansion rate using the lichenometry dataset also available in this data package.格陵兰西部土壤吹蚀地貌的景观位置数据集。野外实测数据包含陡坎长度、陡坎高度与斑块面积。地形高程、坡向、坡度以及至格陵兰冰盖（Greenland Ice Sheet）的距离，均通过极地理空间中心（Polar Geospatial Center）获取的遥感影像计算得到。本数据包中还包含地衣测年数据集，我们依托该数据集计算了斑块扩张速率。
