Ecohydrological metrics of vegetation over Africa at 0.0417° resolution. The data are derived from the Fraction of Vegetation Cover (FVC) product estimated by Trigo et al., 2011 using the retrievals of the geostationary satellite Meteosat Second Generation. The data consist 3 files as: (i) asymptotic minimum and maximum FVC, (ii) FVC integral over decay period, and duration of the corresponding period (iii) the decay rate of FVC during dry-down. Files (ii) and (iii) has variation as a quality diagnostic. In addition, (iii) has number of convergences as another quality diagnostic.

分辨率为0.0417°的非洲地区植被生态水文学指标数据集。本数据集源自Trigo等人2011年基于地球静止卫星新一代气象卫星（Meteosat Second Generation）的反演结果所估算得到的植被覆盖度（Fraction of Vegetation Cover, FVC）产品。该数据集包含3个文件：(i) 渐近最小与最大植被覆盖度；(ii) 衰减期内的植被覆盖度积分值与对应时段的持续时长；(iii) 干旱消退期内植被覆盖度的衰减速率。其中文件(ii)与(iii)均以变异特征作为质量诊断指标；此外，文件(iii)还额外包含收敛次数作为另一项质量诊断指标。数据集参考文献：Küçük Ç.、Koirala S.、Carvalhais N.、Miralles D.G.、Reichstein M.与Jung M.（2020）《利用地球静止卫星表征非洲植被覆盖对水分限制的响应》。
