Shunkalpa Glacier, union of two glaciers namely Kalabaland (10 km long) and Yankchar glaciers (9 km long), is one of the largest glaciers in the Central Indian Himalaya with snout records available since 1886. We aimed to provide a comprehensive status of the glaciological characteristics of the glacier from satellite-based observations by providing the status of the snout fluctuation, surface velocity map, and spatial ice thickness of the glacier. The snout of the Shunkalpa Glacier was receding with a rate of 16 m/yr from 1990 to 2016. The satellite-derived surface velocity and ice thickness of the glacier have spatial variations owing to different topographical characteristics of the glacier. The mean velocity of the Shunkalpa Glacier was 22 m/yr and the mean ice thickness was 109 m. In terms of velocity, the Kalabaland Glacier was more dynamic than the Yankchar Glacier.

印度喜马拉雅中部顺卡尔帕(拉拉姆)冰川冰川学特征卫星综合观测

舒卡尔帕冰川是两个冰川的结合,即 Kalabaland(10 公里长)和 Yankchar 冰川(9 公里长),是印度喜马拉雅中部最大的冰川之一,自 1886 年以来就有记录。我们旨在提供该冰川的综合状况通过提供冰川的口部波动状态、表面速度图和空间冰厚,从卫星观测中了解冰川的冰川学特征。1990年至2016年,舒卡尔帕冰川以16 m/年的速度后退。由于冰川的不同地形特征,卫星推导的冰川表面速度和冰厚存在空间变化。舒卡尔帕冰川的平均速度为 22 m/yr,平均冰厚为 109 m。在速度方面,
