Figure 3From: Comparison between remote sensing and a dynamic vegetation model for estimating terrestrial primary production of Africa GPP, NPP and the NPP/GPP ratio for MOD17 and for LPJ-GUESS. Mean (2000–2010) (a) GPP and (b) NPP (both in kg C m−2 yr−1) for MOD17 and LPJ-GUESS (d, e). Mean (2000–2010) NPP/GPP ratio for MOD17 (c) and LPJ-GUESS (f). Water is blue, urban areas are black, and barren areas are grey). Difference (MOD17-LPJ GUESS) in GPP (g), NPP (h) and NPP/GPP ratio (i).Back to article page
