Vegetation Phenology (Portland)

Phenology dataset *** annual SOS from 1985-2015 for each urban cluster*** annual EOS from 1985-2015 for each urban cluster*** COR: correlation of fitted double logistic curve to the observed EVIS for each pixel. The COR should divided 10000, and it serves as an uncertainty layer to indicate the fitting performance of double logistic model.

物候数据集（Phenology dataset）包含以下内容：各城市集群1985至2015年的年度生长季始期（SOS）数据、各城市集群1985至2015年的年度生长季终期（EOS）数据，以及各像元的拟合双逻辑斯蒂曲线（double logistic curve）与观测EVIS的相关系数（COR）。需将该相关系数除以10000，以此作为不确定性图层，用以表征双逻辑斯蒂模型（double logistic model）的拟合效果。
