COMS GOCI Level-1B: Ocean Color Satellite Imagery for Korean Sea

COMS GOCI Level-1B Data is satellite imagery from the Geostationary Ocean Color Imager onboard the Communication, Ocean and Meteorological Satellite. It provides data in 8 spectral bands with a spatial resolution of about 500 meters over the Korean sea. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Estimating chlorophyll concentration based on spectral band measurements
• Calculating optical diffuse attenuation coefficients based on ocean color data
• Mapping dissolved organic material concentration based on yellow substance detection
• Analyzing suspended particle concentration in the near-surface zone based on spectral reflectance

Strengths

• Data is acquired in 8 spectral bands (6 visible, 2 NIR)
• Provides a spatial resolution of about 500 meters
• Focuses on the Korean sea region

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
