GPP derived by upscaling observations from the current global network of eddy-covariance towers (FLUXNET, Jung et al 2011 Journal of Geophysical Research, 116 G00J07). For the upscaling a model tree ensemble approach was used as described in (Jung, M., Reichstein, M., Bondeau, A. 2009 Biogeosciences, 6). For this dataset the flux partitioning was based on LASSLOP, G. et al. (2010), Global Change Biology, 16: 187–208 This dataset was previously published via the GeoDB data portal hosted at the Max-Planck-Institut for Biogeochemistry, Jena.
