Sensitivity of atmospheric carbon dioxide to dust iron solubility during the last glacial-interglacial cycle: simulation output data

This dataset, archived in Output_simulations.tar.gz, contains the output of model simulations from the study "Sensitivity of atmospheric carbon dioxide to dust iron solubility during the last glacial-interglacial cycle." It is structured to facilitate access to regional (Regional) and global (Global) simulation outputs and associated data derived from various sources of aeolian dust deposition fields.

Organizational Structure:

Global Simulations: Files in this directory are derived from global models and are organized by the source of the dust deposition fields used to force the cGENIE model. The sources include:

• Albani (Albani et al. (2014))
• Lambert ( Lambert et al. (2015))
• Takemura (Takemura et al. (2009))
• Ohgaito (Ohgaito et al. (2018))
• MIROC-ESM (Sueyoshi et al. (2013))
• MRI-CGCM3 (Yukimoto et al. (2012))

Each sub-directory contains simulation outputs for different scaling factors (0.33, 0.67, 1.00, 2.00, 3.00) reflecting variations in dust iron solubility.

Regional Simulations: These directories are structured similarly to the global simulations but are further organized by High Nutrient, Low Chlorophyll (HNLC) regions, which include:

• SA (South Atlantic)
• SP (South Pacific)
• NP (North Pacific)
• CP (Central East Pacific)
• NA (North Atlantic)

Files in these sub-directories detail the outcomes from simulations that apply the same scaling factors as the global simulations but focused on specific oceanic regions noted for their unique biogeochemical characteristics.

Included Files:

fields_biogem_2d.nc: Contains two-dimensional fields of ocean and atmospheric properties, formatted as NetCDF.
fields_biogem_3d.nc: Includes three-dimensional fields of ocean properties at multiple depth levels, provided as NetCDF.
biogem_series_atm_pCO2.res: Outputs the atmospheric concentration of pCO2 from each simulation, crucial for understanding the impacts of varied iron solubility on atmospheric carbon dioxide levels.
