Glacial lake inventory of High Mountain Asia

Glacial lake inventory of High Mountain Asia


The data set integrated glacier inventory data and 426 Landsat TM/ETM+/OLI images, and adopted manual visual interpretation to extract glacial lake boundaries within a 10-km buffer from glacier terminals using ArcGIS and ENVI software, normalized difference water index maps, and Google Earth images. It was established that 26,089 and 28,953 glacial lakes in HMA, with sizes of 0.0054–5.83 km2, covered a combined area of 1692.74 ± 231.44 and 1955.94 ± 259.68 km2 in 1990 and 2018, respectively.The current glacial lake inventory provided fundamental data for water resource evaluation, assessment of glacial lake outburst floods, and glacier hydrology research in the mountain cryosphere region

1. 数据标题是否合适且与数据相符; 相符 2. 数据摘要是否详实且与数据相符; 相符 3. 数据时空范围和分辨率是否与数据相符; 相符 4. 数据格式是否描述正确; 正确 5. 数据知识产权、缩略图等信息是否合适。 合适。 另,细节意见如下: 1、using ArcGIS and ENVI software中的software应为复数形式; 2、The data set integrated glacier inventory data and 426 Landsat TM/ETM+/OLI images, and adopted manual visual interpretation to extract glacial lake boundaries within a 10-km buffer from glacier terminals using ArcGIS and ENVI software, normalized difference water index maps, and Google Earth images. 这一句太长,而且句子结构很有歧义,让不熟悉提取冰湖边界流程的人很容易误以为是排比句,integrated..., adopted..., and normalized.... 建议将其修改为: ..., and adopted some methods including A, B, and C这种格式。 3、It was established that之后更常见的是接从句。 4、respectively.The 结束符号之后需要加空格。 5、glacier hydrology research,貌似glacier hydrology studies更常见。 6、摘要部分最后一句缺少结束符号(.)。 7、关键词中缺少最重要的Glacial lake。
