MCD43D15: Daily Global BRDF Geometric Parameter for MODIS Band 5 at 1km Resolution

MCD43D15 Version 6.1 provides the Bidirectional Reflectance Distribution Function geometric model parameter for MODIS band 5. The dataset is produced daily by NASA using 16 days of combined Terra and Aqua MODIS data at a 30 arc second (approximately 1,000 meter) spatial resolution, temporally weighted to the ninth day. This Climate Modeling Grid product covers the entire globe for use in climate simulation models.

Use Cases

• Deriving land surface albedo for MODIS band 5 based on the geometric parameter in conjunction with isotropic and volumetric parameters.
• Incorporating high-quality, full inversion BRDF results into climate simulation models based on the Climate Modeling Grid format.
• Analyzing daily changes in surface reflectance properties using the temporally weighted, 16-day composite data.
• Applying band-specific quality flags to isolate the highest quality data for science applications as described in the user guide.

Strengths

• Daily global coverage at a consistent 30 arc second (1,000 meter) resolution.
• Version 6.1 incorporates calibration improvements including response-versus-scan angle changes and polarization correction.
• Data is temporally weighted to the ninth day of a 16-day composite, providing a consistent temporal reference.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Each product file contains just one data layer, which may complicate multi-parameter analysis.
