Figure 4: Regional GPP estimates of LUE models.
From: Differentiating moss from higher plants is critical in studying the carbon cycle of the boreal biome

(a) The lowest, (b) the highest and (c) mean values of GPP estimates considering the impacts of moss based on the EC-LUE-2p model. (d) The difference in GPP simulations between the original EC-LUE and the EC-LUE-2p models (mean values). The low and high estimates represent the EC-LUE-2p estimates with 95% confidence. The original EC-LUE model does not consider the impacts of moss. The unit of GPP is g C m−2 per year.
