Soil data at station Bayelva (2020, level 1)

Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the Bayelva Site at Ny-Ålesund, Svalbard, where meteorology, energy balance components and subsurface observations have been made for more than the last 20 years. The data provide observations of temporally variable parameters that mitigate energy fluxes between permafrost and the atmosphere, such as active layer and permafrost temperature, soil volumetric water content and soil bulk electrical conductivity. They are suitable for use in integrating, calibrating and testing permafrost as a component in Earth System Models. The resulting quality-controlled dataset is unique in the Arctic and serves as a baseline for future studies.

理解多年冻土（permafrost）过程与变化需要长期观测数据集。本数据集是斯瓦尔巴群岛新奥尔松Bayelva站点现有数据集的延续，该站点已开展气象、能量平衡分量及地下观测逾20年。数据集包含多年冻土与大气间能量通量调节相关的时空变化参数观测，例如活动层（active layer）与多年冻土温度、土壤体积含水量及土壤体积电导率。该数据集适用于地球系统模型（Earth System Models）中多年冻土模块的整合、校准与测试。经过质量控制的最终数据集在北极地区具有独特性，可作为未来研究的基准。
