【摘要】 ​全球淡水变量该数据集由标准化的1公里网格中的近乎全球的、空间上连续的和特定淡水的环境变量组成。我们沿HydroSHEDS河流网络为每个网格单元划定了子流域,并使用各种指标(平均值、最小值、最大值、范围、总和、反距离加权平均值和总和)对每个网格单元的上游环境(气候、地形、土地覆盖、地表地质和土壤)进行总结。随后对全球湖泊和湿地数据库中与河网相连的单个湖泊和水库的所有变量进行了平均。月度气候变...

全球淡水变量
该数据集由标准化的1公里网格中的近乎全球的、空间上连续的和特定淡水的环境变量组成。我们沿HydroSHEDS河流网络为每个网格单元划定了子流域,并使用各种指标(平均值、最小值、最大值、范围、总和、反距离加权平均值和总和)对每个网格单元的上游环境(气候、地形、土地覆盖、地表地质和土壤)进行总结。随后对全球湖泊和湿地数据库中与河网相连的单个湖泊和水库的所有变量进行了平均。月度气候变量按照 "生物气候 "框架被归纳为19个长期气候变量。前言 – 床长人工智能教程
