Model output for "Enrichment of ammonium in the future ocean threatens diatom productivity"
Description
Each netcdf file (.nc) contains model output from simulations performed with the
NEMO-PISCES global ocean-biogeochemistry model. These simulations were
forced by physical output from the IPSL-CM5A Earth System Model, which
performed both the natural (no anthropogenic activities) and RCP8.5 scenarios.

Naming convention:
"ETOPO" - refers to being on a regular 1x1 degree horizontal grid
"nitri" - refers to the developed PISCES model with explicit two-step nitrification
"kaoafer00" - refers to no iron limitation of AOA
"1m" - refers to the timestep resolution, here 1 month. Thus, all data presented here is monthly averaged values.
"2ndpicontrol" - refers to preindustrial control run
"acid" - refers to the control run + ocean acidification
"warm" - refers to the control run + warming
"circ" - refers to the control run + circulation change
"full" - refers to the control run + ocean acidification + warming + circulation change
"picontrolalt" - refers to preindustrial control run (alternative pH parameterisation)
"acidalt" - refers to the control run + ocean acidification (alternative pH parameterisation)
"fullalt" - refers to the control run + ocean acidification + warming + circulation change (alternative pH parameterisation)
