ABoVE: Climate Drivers of Pan-Arctic Tundra Vegetation Productivity, 1982-2015

This dataset provides a summary of potential climate drivers of Arctic tundra vegetation productivity that have been compiled for growing seasons from 1982 to 2015. The scale of interest is the entire pan-arctic non-alpine tundra and the continental subdivisions of the North American and the Eurasian Arctic North of 70 degrees. These climate drivers include (1) maximum normalized difference vegetation index (MaxNDVI) and time-integrated NDVI (TI-NDVI), (2) summer sea ice concentrations, (3) oceanic heat content, (4) land surface temperature, and (5) summer warmth index (SWI). Data are provided variously as timeseries and weekly and bi-weekly averages over selected time ranges and study regions with calculated trends and trend significance. Data collected over 33 years were compiled to observe seasonal trends of vegetation productivity and to detect dynamics between arctic vegetation and climate drivers.本数据集汇总了1982年至2015年生长季期间，与北极苔原植被生产力相关的潜在气候驱动因子。本研究关注的空间尺度为北纬70度以北的泛北极非高山苔原，以及北美与欧亚北极区域的大陆分区。纳入分析的气候驱动因子包括：(1) 最大归一化差分植被指数（MaxNDVI）与时间积分归一化差分植被指数（TI-NDVI）；(2) 夏季海冰浓度；(3) 海洋热含量；(4) 地表温度；(5) 夏季温暖指数（SWI）。数据以多种形式提供，涵盖选定研究区域与时间范围内的时间序列数据，以及周度、双周平均数据，并附带计算得到的趋势及其显著性水平。本次研究汇总了33年的观测数据，旨在分析植被生产力的季节变化趋势，并探究北极植被与气候驱动因子之间的动态关联。
