Non-growing season CH4 fluxes over arctic and boreal environments

Non-growing season CH4 fluxes over boreal and arctic environments using the snowpack diffusion gradient method. This dataset consists of 802 snowpack diffusion gradient measurements made over five different boreal and arctic ecosystems in Canada and Finland: closed-crown coniferous boreal forest, open-crown coniferous boreal forest, erect tundra shrubs, prostrate tundra shrubs and boreal wetlands. Snow and soil data are incorporated into the dataset as environmental variables.

采用积雪扩散梯度法（snowpack diffusion gradient method）测定的加拿大及芬兰境内寒带与北极环境非生长季甲烷（CH4）通量数据集。本数据集包含802组积雪扩散梯度测量数据，采集自加拿大与芬兰的5类不同寒带及北极生态系统，分别为郁闭冠层针叶寒带林、疏冠层针叶寒带林、直立型冻原灌丛、匍匐型冻原灌丛与寒带湿地。数据集纳入积雪与土壤数据作为环境变量。
