Model output for "Enrichment of ammonium in the future ocean threatens diatom productivity"

Each netcdf file (.nc) contains model output from simulations performed with the<br> NEMO-PISCES global ocean-biogeochemistry model. These simulations were<br> forced by physical output from the IPSL-CM5A Earth System Model, which <br> performed both the natural (no anthropogenic activities) and RCP8.5 scenarios.
