Global satellite-derived measurements of particulate organic carbon concentration in ocean surface waters. The data is produced by NASA's OB_CLOUD organization using the Terra MODIS sensor and is based on algorithms by D. Stramski (2007) and Stramski et al. (2022). This version 2022.0 of the data suite is used to quantify surface carbon stocks.
Use Cases
- Quantify surface ocean carbon stocks based on particulate organic carbon concentration.
- Support biogeochemical and export-flux studies based on ocean-color reflectance data.
- Provide ecological context alongside other ocean variables like chlorophyll-a and sea surface temperature mentioned in the description.
Strengths
- Data is derived from the Terra MODIS satellite sensor, a well-established source for global Earth observation.
- Algorithm is based on peer-reviewed work by D. Stramski (2007) and updated for PACE (2022).
- The dataset is part of a suite providing context alongside other key ocean variables like chlor_a and SST.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count, file formats, and data size are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
