MOBO-DIC_MPIM: Monthly Climatology of Oceanic Dissolved Inorganic Carbon (2004-2017)

Global ocean data from the Max Planck Institute for Meteorology provides mapped, gap-filled fields of dissolved inorganic carbon (DIC) in the water column. The dataset is a monthly climatology based on observations from 2004 through 2017, produced using a self-organizing map and feed-forward network (SOM-FFN) method extended to four dimensions. An ensemble mean from ten bootstrapping runs provides the final DIC field, with an ensemble spread representing methodological uncertainty.

Use Cases

• Modeling ocean carbon uptake and storage based on mapped DIC climatology.
• Analyzing seasonal cycles of dissolved inorganic carbon based on monthly resolution.
• Assessing uncertainty in carbon system estimates based on the provided ensemble spread.
• Studying vertical carbon distribution in the water column based on the four-dimensional (latitude, longitude, time, depth) mapping grid.

Strengths

• Data is gap-filled using an advanced SOM-FFN method, providing continuous global fields.
• Includes an uncertainty estimate defined as the standard deviation across a 10-run ensemble.
• Covers a 14-year observational period from 2004 to 2017.
• Resolves data in four dimensions: latitude, longitude, time, and depth.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
