Land system changes of terrestrial tipping elements on Earth under global climate pledges: 2000-2100

The land system changes dataset includes five maps of land system maps for tipping elements on Earth for the years 2000, 2010, 2020, and 2100, under two climate scenarios: reference and climate pledges. The dataset was produced by integrating the GCAM model with a modified version of CLUMondo. It offers a spatial resolution of 1 km and a thematic resolution comprising 30 categories, which combine three density types and ten land cover types. The land system types corresponding to the values in the raster data attribute table are detailed in the Data Records section of our submitted manuscript.

土地系统变化数据集包含2000年、2010年、2020年及2100年两个气候情景（参考情景与气候承诺情景）下的5幅地球临界要素（tipping elements）土地系统图。该数据集通过整合GCAM模型与CLUMondo的改进版本生成，空间分辨率为1千米，主题分辨率包含30个类别，这些类别结合了3种密度类型与10种土地覆盖类型。栅格数据属性表中数值对应的土地系统类型详见我们已提交手稿的“数据记录”部分。
