MODIS/Terra Surface Reflectance Daily Global 0.05-Degree Climate Modeling Grid

MODIS/Terra Surface Reflectance Daily L3 Global 0.05Deg CMG V061 provides atmospherically corrected surface spectral reflectance estimates for MODIS Bands 1-7 at a 5600-meter pixel resolution. The product contains 25 layers, including reflectance bands, brightness temperature from thermal bands, and quality assurance data, and is formatted on a Climate Modeling Grid for climate simulations. This dataset is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Calibrating climate models based on daily global surface reflectance data.
• Analyzing long-term land surface changes based on atmospherically corrected spectral bands.
• Assessing data quality for climate studies using the included Quality Assurance (QA) layers.
• Integrating surface radiative properties into Earth system models based on the Climate Modeling Grid (CMG) format.

Strengths

• Provides 25 data layers, including 7 spectral reflectance bands and 4 thermal brightness temperature bands.
• Data is atmospherically corrected for gasses, aerosols, and Rayleigh scattering.
• Version 6.1 includes calibration improvements such as polarization correction and RVS approach updates.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Known issues exist and require consultation of the external MODIS/VIIRS Land Quality Assessment website.
