改变地球植被覆盖会影响地表的生物物理特性,并最终影响当地气候。取决于植被变化的具体类型和背景气候,由此产生的相互竞争的生物物理过程可产生净变暖或净变冷效应,这种效应在空间和季节上可能进一步变化。由于气候影响的不确定性和缺乏强有力的观测,陆地气候政策尚未考虑到生物物理影响。在这里,我们提出了一个数据集的基础上,卫星遥感观测,提供了潜在的变化i)的完整的表面能量平衡,ii)在全球范围内,和iii)为多个植被过渡,现在将需要全面评估的土地为基础的缓解计划。我们预计,这一数据集将为基准地球系统模型提供宝贵的信息,以评估土地覆盖变化的未来情景,并制定执行考虑生物物理土地过程的减缓计划所需的监测、报告和核查准则。
Changing the vegetation cover of the Earth has impacts on the biophysical properties of the surface and ultimately on the local climate. Depending on the specific type of vegetation change and on the background climate, the resulting competing biophysical processes can have a net warming or cooling effect, which can further vary both spatially and seasonally. Due to uncertain climate impacts and the lack of robust observations, biophysical effects are not yet considered in land-based climate policies. Here we present a dataset based on satellite remote sensing observations that provides the potential changes i) of the full surface energy balance, ii) at global scale, and iii) for multiple vegetation transitions, as would now be required for the comprehensive evaluation of land based mitigation plans. We anticipate that this dataset will provide valuable information to benchmark Earth system models, to assess future scenarios of land cover change and to develop the monitoring, reporting and verification guidelines required for the implementation of mitigation plans that account for biophysical land processes.
