MCD43D67: Daily Global Nadir-Adjusted Reflectance for MODIS Band 6 at 1km

Global daily land surface reflectance data produced by NASA using 16 days of Terra and Aqua MODIS satellite observations, weighted to a central date. The dataset provides Nadir BRDF-Adjusted Reflectance (NBAR) for MODIS band 6 at a 30 arc-second (approximately 1km) resolution, formatted for climate simulation models. The Version 6.1 product incorporates calibration improvements including response-versus-scan angle and polarization corrections.

Use Cases

• Modeling land surface energy budgets based on daily nadir-adjusted reflectance.
• Monitoring vegetation changes based on the NBAR algorithm's removal of view angle effects.
• Assessing surface radiative properties for climate grids based on the 1km Climate Modeling Grid (CMG) product.
• Integrating corrected reflectance into land cover classification models based on the band-specific quality flags.

Strengths

• Daily global coverage at a consistent 1km spatial resolution.
• Data incorporates 16 days of observations for temporal stability, weighted to a central ninth day.
• Version 6.1 includes specific calibration improvements for Terra and Aqua MODIS sensors.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Each product file contains just one data layer, which may complicate multi-band analysis.
• Row count is unknown, which may limit suitability assessment.
