Global Ocean Color Measurements from ADEOS-II Satellite

JAXA's ADEOS-II satellite provides daily, 9 km resolution global ocean color data from its GLI sensor. The dataset includes derived statistics for chlorophyll-a concentration, attenuation at 490 nm, suspended solid concentration, and CDOM absorption at 440 nm. This version 2 product was last updated with data from October 2003.

Use Cases

• Modeling phytoplankton biomass distribution by analyzing daily chlorophyll_a concentration fields.
• Assessing coastal water quality and turbidity using suspended solid concentration and attenuation at 490 nm measurements.
• Tracking dissolved organic matter in ocean waters through CDOM absorption at 440 nm data.
• Conducting temporal trend analysis on ocean biological parameters using the daily, 8-day, and monthly statistical summaries.

Strengths

• Global spatial coverage from a satellite with a 1600 km swath.
• Includes derived statistical summaries (sum, square sum, max, min) for each measured parameter.
• Data is available at multiple temporal resolutions: 1-day, 8-day, and 1-month statistics.

Limitations

• Data collection ended in 2003, limiting analysis to historical conditions.
• Spatial resolution of 9 km may be too coarse for studying fine-scale coastal or estuarine processes.
• Specific row counts, file sizes, and sample data availability are unknown.
