Fig. 3

Determination coefficient (R2) of the regression of annual gross primary production (GPP) against the integral vegetation indices (VIs) or mean VIs for the growing-season defined by different thresholds. NDVIB: broadband normalized difference vegetation index, EVIB: broadband enhanced vegetation index, NIRvB: broadband near-infrared albedo of vegetation, NDVIM: MODIS normalized difference vegetation index, EVIM: MODIS enhanced vegetation index, NIRvM: MODIS near-infrared reflectance of vegetation
