“一带一路”积雪持续日数数据集（2000-2024年）

基于多源遥感数据，采用MARS模型结合地类特征的方法进行积雪自动识别，生成了一套“一带一路”区域的积雪面积数据。在此基础上，计算积雪持续日数。积雪日数定义为一个水文年上观测到积雪的天数之和。Based on multi-source remote sensing data, automatic snow cover identification was conducted using the MARS model combined with land cover features, and a set of snow cover area datasets for the Belt and Road Initiative (BRI) region was generated. On this basis, the snow cover duration days were calculated, which is defined as the total number of days with observed snow cover within a hydrological year.
