Gridded data of carbon fluxes by Alaska black spruce forest

The gridded carbon fluxes were calculated by an empirical model (SCAPE; Ueyama et al., 2010); carbon fluxes of GPP and Ecosystem Respiration (RE) were empirically up-scaled with the eddy covariance data observed at the UAF site and satellite remote sensing (Modereta Resolution Spectral Radiometer). The model calculated the fluxes between 2003 and 2006 for black spruce forests in Alaska with a spatial resolution of 250 m.网格化碳通量通过经验模型SCAPE（Ueyama等，2010）计算得到；总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, RE）的碳通量，依托UAF站点观测的涡度协方差数据以及搭载中分辨率光谱辐射计（Modereta Resolution Spectral Radiometer）的卫星遥感数据完成经验性尺度上推。该模型针对阿拉斯加地区的黑云杉林，计算了2003至2006年间的碳通量，空间分辨率为250米。
