MODIS/Terra Ocean Reflectance: Daily Global 1km Gridded Satellite Data

MODOCGA Version 6 Level 2 Gridded Lite (L2G-lite) Ocean Reflectance product provides daily surface spectral reflectance estimates from Terra MODIS bands 8-16, corrected for atmospheric conditions. The product, decommissioned on July 31, 2023, is a daily land product with a 1-kilometer pixel size and stores the 'best available pixel' in a hierarchical data format. This data was produced by the National Aeronautics and Space Administration.

Use Cases

• Modeling ocean color and phytoplankton concentrations based on surface spectral reflectance data.
• Monitoring daily changes in coastal water properties based on atmospherically corrected satellite bands.
• Analyzing the 'best available pixel' for temporal consistency in land-ocean interface studies.

Strengths

• Data is atmospherically corrected for gasses, aerosols, and Rayleigh scattering.
• Provides daily global coverage at a 1-kilometer spatial resolution.
• Stores multiple observations per pixel in a hierarchical format, preserving data from qualifying passes.

Limitations

• The product was decommissioned on July 31, 2023, and is no longer updated.
• Column-level documentation is absent; field semantics must be inferred after download.
• Known issues exist and require consultation of an external quality assessment website.
