Figure 4From: Comparison between remote sensing and a dynamic vegetation model for estimating terrestrial primary production of Africa GPP and NPP per land cover class. (a) Totaled MOD17 and LPJ-GUESS GPP and NPP per land cover class, where GPP differs significantly (t-test p < 0.01) for all land cover types except for mixed forest and savannas. NPP differs significantly (t-test p < 0.01) for all land cover types. (b) Mean GPP and NPP per land cover class and unit area. Yellow bars denote NPPCombined (MOD17 GPP – Ra from LPJ-GUESS).Back to article page
