The hypothesis and analysis for GPP in urban gridcells

Caption

A. Vegetation within an urban gridcell (URV or GPP) is affected by (1) expansion of urban impervious surface (UIS), which is a metric for urban expansion (UE), and (2) urban management and climate (UMC). H0, H1, and H2 (red, yellow, and blue lines) are the three-basic hypotheses for analyzing the offsetting effects of urbanization on GPP. B: Interannual trend of urban GPP during 2000–2016. C: Corresponding result after normalization of urban GPP and nonurban GPP
