摘要:

蒙古高原主体区域指蒙古国与我国内蒙古自治区所辖区域,地处欧亚大陆干旱-半干旱过渡带,是全球气候变化和冰冻圈环境变化的敏感区域。作者基于Google Earth Engine平台,利用1990-2024年Landsat系列地表反射率数据,结合DEM高程约束、NDSI、NDVI、NDWI光谱指数和固定非雪端元与分级雪端元相结合的多端元光谱混合分析(MESMA)策略,研发了蒙古高原主体区域30-m夏季积雪覆盖度数据集(1990-2024)。数据集内容包括:1990-2024年逐年夏季积雪覆盖度栅格数据,空间分辨率为30 m。数据集存储为.tif格式,由226个数据文件组成,数据量为4.18 GB(压缩为1个文件,198 MB)。该数据集可以为蒙古高原冰冻圈变化、水文过程模拟、生态环境评估和气候变化响应研究等提供基础数据。
