Synthesis of soil-air temperature and vegetation measurements in the pan-Arctic. 1990-2016

This data was compiled for a data synthesis of plot scale studies aimed at understanding the impact of vegetation on soil-air temperature coupling throughout the permafrost region. The aim of this study was to determine whether vegetation impacts on soil temperature were consistent across a broad geographic scope and multiple studies. The data synthesis originated from discussions in the annual Permafrost Carbon Network meeting recognizing the need for a comprehensive assessment of plot scale studies of vegetation and soil temperature. Observations were compiled from 32 collaborators with 235 unique locations, and were initially collected as part of individual field studies lead by each collaborator. All soil and air temperature data were averaged at the daily timescale prior to inclusion in this data set.

本数据集系为开展样地尺度（plot scale）研究的综合分析而汇编，旨在解析多年冻土区（permafrost region）内植被对土壤-空气温度耦合过程的影响。本次综合分析的研究目标为明确：植被对土壤温度的影响是否在广泛地理范围内及多项独立研究中保持一致。本次综合分析缘起于年度多年冻土碳网络（Permafrost Carbon Network）会议中的研讨，与会者意识到亟需对植被与土壤温度的样地尺度研究开展全面评估。本数据集的观测数据来自32位合作者提供的235个独立样点，原始数据最初由各合作者主导的独立野外研究采集所得。所有土壤与空气温度数据在纳入本数据集前，均已按日尺度完成平均处理。
