Daily Global BRDF Geometric Parameter for MODIS Band 3

MODIS/Terra+Aqua BRDF/Albedo Parameter3 Band3 Daily L3 Global 30ArcSec CMG V061 provides the geometric parameter for deriving bidirectional reflectance and albedo for MODIS band 3. LPCLOUD produces this dataset daily using 16 days of MODIS data at 30 arc second resolution. Data are temporally weighted to the ninth day of the acquisition period.

Use Cases

• Deriving BRDF and albedo values for MODIS band 3 using the geometric parameter alongside isotropic and volumetric parameters.
• Assessing surface reflectance anisotropy for climate modeling grids at 30 arc second resolution.
• Filtering data quality for band 3 using the band-specific quality flags described in the user guide.
• Integrating geometric parameter data with other MCD43D files (MCD43D01 through MCD43D30) for multi-band analysis.

Strengths

• Daily production using 16 days of Terra and Aqua MODIS data for temporal stability.
• Global coverage at 30 arc second (approximately 1,000 meter) resolution suitable for climate simulation models.
• Separate files for each model parameter and band facilitate focused analysis.

Limitations

• Each product file contains only one data layer, requiring multiple file downloads for full parameter sets.
• Known issues exist, requiring consultation of the MODIS/VIIRS Land Quality Assessment website.
• The large file size per single-layer product may pose storage and processing challenges.
