A global monthly climatology of total inorganic carbon and total alkalinity on a 1° x 1° x 32-layer grid. The dataset was created by Catherine Goyet of Université de Perpignan using interpolation methods applied to high-quality data from programs like WOCE, JGOFS, and OACES. It is designed to initialize three-dimensional ocean-atmosphere carbon dioxide models.
Use Cases
- Initializing 3-D ocean carbon fields in global climate models based on the described interpolation methodology.
- Analyzing spatial variation in total alkalinity and total inorganic carbon below the mixed layer.
- Diagnostic studies of the ocean-atmosphere carbon dioxide system using the gridded monthly climatology.
Strengths
- Derived from high-quality data sets from major oceanographic programs (WOCE, JGOFS, OACES).
- Provides a global 3-D grid at 1° x 1° horizontal and 32-layer vertical resolution.
- Offers monthly temporal resolution for the computed carbon fields.
Limitations
- Data is limited to waters below the deepest winter mixed layer depths.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
