Satellite-derived particulate organic carbon (POC) concentration data quantifies surface carbon stocks in the global ocean. The dataset originates from the ADEOS-I Ocean Color and Temperature Scanner (OCTS) instrument, processed by OB_CLOUD. The primary data record concludes in June 1997.
Use Cases
- Modeling surface carbon stocks by analyzing the global poc concentration field.
- Studying biogeochemical cycles by correlating poc with other ocean-color variables like chlor_a and bbp.
- Investigating carbon export flux using poc concentration as a key input parameter.
- Providing ecological context by comparing poc spatial patterns with sea surface temperature (SST) data.
Strengths
- Derived from the ADEOS-I OCTS satellite instrument, a dedicated ocean color sensor.
- Provides a global spatial coverage of ocean surface POC.
- Based on the Stramski (2007) algorithm, a established method for POC retrieval.
Limitations
- Temporal coverage is limited, with the last update in 1997.
- Data is binned to a Level-3 product, which may have lower spatial resolution than raw data.
- Algorithm version (2022.0) suggests reprocessing, but the underlying sensor data is over 25 years old.
