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

Authors/Creators

  • 1. Carnegie Institution for Science

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)
