MODIS/Terra Surface Reflectance Daily Global 250m SIN Grid

Daily global surface reflectance data from the Terra MODIS satellite at 250-meter resolution, corrected for atmospheric conditions. The dataset, produced by NASA, includes spectral bands, quality assurance, and observation layers, with the Version 6 product decommissioned on July 31, 2023. Users are directed to the updated Version 6.1 product.

Use Cases

• Monitoring land surface changes based on daily 250-meter reflectance estimates.
• Assessing atmospheric correction quality based on the included QA and observation layers.
• Developing vegetation indices in conjunction with the 500-meter MOD09GA product's geometry information.
• Analyzing surface radiative properties for climate models based on the BRDF-constrained algorithms.

Strengths

• Provides daily global coverage at 250-meter spatial resolution.
• Includes quality assurance and five observation layers for data validation.
• Atmospherically corrected for gasses, aerosols, and Rayleigh scattering.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Known issues include potential striping from a dead detector in 2000 and possible incorrect aerosol flagging in Collection 6.
• Column-level documentation is absent; field semantics must be inferred after download.
