1980-2018全球陆地水分利用效率
收藏资源简介:
全球生态系统水分利用效率(WUE)数据集,是由PML-V2模型的GPP(生态系统总初级生产力),ET(生态系统蒸散发)计算得到,其计算公式为WUE=GPP/ET。本数据集是年数据,空间分辨率为0.05°,时间范围为2003—2018年共16期。b. 数据的时间范围 2003—2018年 c. 数据的空间范围、投影方式 空间范围:全球 投影方式:WGS84 d. 数据的量 数据量合计约1.2GB e. 数据类型(文献、属性、矢量、栅格、文本等) 栅格,tiff格式 f. 数据更新的频度 每年更新 g. 缩略图(反应数据集内容或观测过程、场景等的示意图)
The Global Ecosystem Water Use Efficiency (WUE) dataset is calculated based on Gross Primary Productivity (GPP, ecosystem total primary productivity) and Evapotranspiration (ET, ecosystem evapotranspiration) derived from the PML-V2 model, with the calculation formula: WUE = GPP/ET. This is an annual dataset with a spatial resolution of 0.05°, covering 16 periods from 2003 to 2018. b. Temporal Range: 2003–2018 c. Spatial Scope and Projection Method: Global spatial scope; Projection method: WGS84 d. Data Volume: The total data volume is approximately 1.2 GB e. Data Type: Raster, in TIFF format f. Update Frequency: Updated annually g. Thumbnail: Schematic diagram reflecting the dataset content, observation process or related scene
