Field Data on Soils, Vegetation, and Fire History for Alaska Tundra Sites, 1972-2020

This dataset, titled the Synthesized Alaskan Tundra Field Database (SATFiD), provides a comprehensive collection of in-situ field data compiled from 37 existing datasets resulting from field surveys conducted at Alaska tundra sites between 1972 to 2020. The data were harmonized prior to being included in this dataset. The variables include active layer thickness, vegetation cover (by plant functional types), soil moisture and temperatures, as well as the wildfire history. SATFiD provides a unique lens into various long-term ecological processes within the tundra (such as the fire-permafrost-vegetation interactions) under a rapidly changing climate.

本数据集名为模拟阿拉斯加苔原野外数据库（SATFiD），汇聚了自1972年至2020年在阿拉斯加苔原地区开展实地调查所形成的37个现有数据集的综合性现场数据集。在纳入本数据集之前，数据已进行调和处理。数据变量包括活动层厚度、植被覆盖（按植物功能型分类）、土壤湿度和温度，以及野火历史。SATFiD为研究在快速变化的气候条件下，苔原中各种长期生态过程（如火灾-永久冻土-植被相互作用）提供了一个独特的视角。
