Particulate Organic Carbon concentration data derived from ocean-color reflectance measured by the VIIRS instrument on the NOAA-20 satellite. The dataset supports quantification of surface carbon stocks and biogeochemical studies alongside related variables like chlorophyll-a and sea surface temperature. It is produced by OB_CLOUD and represents version 2022.0.
Use Cases
- Quantify surface carbon stocks by analyzing the 'poc' concentration variable across global ocean regions.
- Support biogeochemical flux studies by correlating 'poc' data with other geophysical variables like chlor_a and SST.
- Provide ecological context for marine productivity by mapping 'poc' concentrations alongside bbp and Kd_490 data.
- Validate and improve satellite-derived POC algorithms, such as the Stramski 2007 (443/555) version.
Strengths
- Provides a globally binned Level-3 product, offering spatially aggregated data for analysis.
- Includes a key biogeochemical variable (poc) used in major studies and aligned with PACE mission standards.
Limitations
- Specific row count, geographic resolution, and temporal coverage for version 2022.0 are unknown.
- Relies on satellite ocean-color reflectance, which can be affected by atmospheric conditions and cloud cover.
