Global Ocean Particulate Inorganic Carbon from ADEOS-I Satellite

Particulate Inorganic Carbon (PIC) concentration data derived from ocean-color reflectance using the Balch & Gordon algorithm. The dataset, produced by OB_CLOUD, provides a global binned product from the ADEOS-I OCTS mission. Data collection ended in June 1997.

Use Cases

• Detect coccolithophore blooms by analyzing spatial and temporal patterns in the `pic` concentration field.
• Assess marine carbonate cycling by correlating the `pic` variable with sea surface temperature and other biogeochemical parameters.
• Validate and improve ocean-color algorithms for PIC retrieval by comparing this historical dataset with newer satellite missions.
• Study optical backscatter in the ocean by using `pic` concentration as a key input for bio-optical models.

Strengths

• Provides a specific geophysical variable (`pic`) for a key component of the marine carbon cycle.
• Data is processed to a standardized Level-3 binned format, facilitating large-scale analysis.

Limitations

• Data is from a single mission (ADEOS-I) with collection ending in 1997, limiting temporal recency and continuity.
• Algorithm uncertainties increase in optically complex coastal waters and under high aerosol or glint conditions, as noted in the description.
• The exact spatial resolution, row count, and comprehensive quality flag details are unknown from the provided input.
