Daily Global BRDF Volumetric Parameter for MODIS Band 3

MCD43D08 Version 6.1 provides the volumetric parameter for the Bidirectional Reflectance Distribution Function (BRDF) model for MODIS band 3. This daily product is generated using 16 days of Terra and Aqua MODIS data at a 30 arc-second (1,000 meter) resolution and is temporally weighted to the ninth day. The dataset is produced by LPCLOUD for use in global climate simulation models.

Use Cases

• Calculate surface albedo for MODIS band 3 by combining the volumetric parameter with isotropic and geometric parameters.
• Assess daily changes in land surface reflectance properties using the temporally weighted ninth-day data.
• Integrate the volumetric parameter into climate simulation models to improve radiative forcing estimates.
• Filter data quality for scientific applications using the band-specific quality flags described in the user guide.
• Study the volumetric scattering component of surface reflectance across the globe at 1,000-meter resolution.

Strengths

• Daily global coverage at 30 arc-second resolution.
• Data are produced using 16 days of MODIS observations from both Terra and Aqua satellites for stability.
• Separate files for each model parameter and band facilitate focused analysis.

Limitations

• Each product file contains only one data layer, requiring multiple files for complete analysis.
• Known issues exist, requiring users to consult external assessment websites.
• The large file size per layer may pose challenges for storage and processing.
