The dataset contains the fields that have been used in the Barrier et al. (2023) paper It contains: NEMO/PISCES 3D fields Zonal and meridional velocities Temperature Plankton concentration Chlorophyll APECOSM 2D and 3D fields for the epipelagic community Vertically integrated biomass density Size-binned 3D biomass For the three size classes described in the paper Trend terms (predation, growth, zonal and meridional advection/diffusion) Growth rate Functional response Mortality rates For space issue, the data provided here have been extracted for the Pacific ocean and for the upper 250m. They also have been strongly compressed. Scripts to regenerate the outputs are provided here: https://doi.org/10.5281/zenodo.7729755
