Abstract: The glacier area of West China is more sensitive to climate change response and the magnitude of change varies widely. Since the second glacier inventory in China, there has been a lack of systematic investigation of glacier in West China. Based on the second glacier inventory data of China, this dataset has completed the extraction of glacier boundaries, quality checking of boundaries, uncertainty analysis of area and updating of glacier attributes in West China in 2018 by using various data sources such as 315 Landsat remote sensing images and SRTM, combined with processing software of ArcGIS and Google Earth, and through manual visual interpretation. The results show that 53238 glaciers existed in West China in 2018, with a total area of 47174.21 ± 19.93 km2, area error of ±0.04% of the total glacier area. In southeastern Tibet, where the second glacier inventory in China is not yet complete, there are 13066 glaciers with a total area of 7611.25±4.64km2. This dataset provides data support for studies related to the exploration of glacier changes and glacier response to climate change in West China.
