MCD43D13: Daily Global BRDF Isotropic Parameter for MODIS Band 5 at 1km Resolution

Daily global data produced using 16 days of Terra and Aqua MODIS observations, temporally weighted to the ninth day. The MCD43D13 dataset provides the Bidirectional Reflectance Distribution Function (BRDF) isotropic parameter for MODIS band 5 at a 30 arc second (1,000 meter) resolution, produced by NASA. This Climate Modeling Grid product is designed for use in climate simulation models.

Use Cases

• Deriving BRDF/Albedo values for MODIS band 5 based on the isotropic, volumetric, and geometric parameters.
• Incorporating high-quality, full inversion results into climate simulation models as described in the User Guide.
• Analyzing daily surface reflectance properties for climate research using the 30 arc second Climate Modeling Grid.
• Isolating data quality for science applications using the band-specific quality flags mentioned in the description.

Strengths

• Daily production using 16 days of Terra and Aqua MODIS data for temporal stability.
• Global coverage at 30 arc second (1,000 meter) resolution, suitable for climate models.
• Version 6.1 includes calibration improvements such as RVS changes and polarization correction for reflective solar bands.

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.
• Data may reflect temporal weighting and sensor-specific biases inherent to the MODIS platform.
