Input Layers: Predicted Change in Suitable Habitat (PCSH) GCM 4.5 & 8.5

Data was obtained from the Climate Change Tree Atlas using GCM4.5 and GCM 8.5 layers, with values representing the difference in habitat verses current relative importance values. For each species, a layer was generated to account for each of these scenarios. From the original layers, cells valued at 200 (cells that were not modeled) and 300 (cells that weren’t suitable under the current scenario) were removed and remaining values were rescaled to a -100 to 100 scale.

本数据集源自《气候变化树木图谱》（Climate Change Tree Atlas），采用全球气候模式（Global Circulation Model，GCM）4.5与GCM 8.5情景下的栅格图层，其数值代表栖息地适宜性与当前相对重要性值的差值。针对每个物种，我们针对上述两类气候情景分别生成了对应栅格图层。在原始图层中，栅格值为200（未参与建模的栅格单元）与300（当前情景下不适宜的栅格单元）的单元将被移除，剩余数值将被重新缩放至-100至100的数值区间。
