From: A traceability analysis system for model evaluation on land carbon dynamics: design and applications
The global distribution of the variations of the traceable variables simulated by seven models from CMIP6 for the historical period of 1850–2014. a–f The standard deviation of net primary productivity (NPP), gross primary productivity (GPP), carbon use efficiency (CUE), carbon residence time, baseline carbon residence time, and environmental scalars, respectively
