<b>MSDDT: </b><b>A Multi-method Global Snow Drought Dataset and Toolbox</b>

The Multi-method Global Snow Drought Dataset and Toolbox (MSDDT) – an integrated framework comprising an open-source analytical toolkit (MSDT) and a comprehensive global dataset (MSDD). MSDT features an intuitive interface enabling multi-temporal scale analysis (daily to yearly) of snow drought patterns, complemented by built-in visualization tools and data download functionalities. Its derivative MSDD dataset provides global snow drought metrics including their occurrence, type and intensity at 0.25° resolution (1980-2024).多方法全球雪干旱数据集与工具箱（Multi-method Global Snow Drought Dataset and Toolbox，MSDDT）是一套整合型框架，涵盖开源分析工具箱（MSDT）与综合全球数据集（MSDD）两大组成部分。MSDT配备直观的交互界面，可实现雪干旱格局的多时间尺度（每日至年度）分析，并内置可视化工具与数据下载功能。其衍生数据集MSDD提供了1980—2024年期间、分辨率为0.25°的全球雪干旱指标，涵盖雪干旱的发生情况、类型与强度。
