MODIS BRDF Isotropic Parameter for Band 3 Daily Global Climate Grid

MCD43D07 Version 6.1 provides the isotropic parameter for the Bidirectional Reflectance Distribution Function and Albedo model for MODIS band 3. It is produced daily by LPCLOUD using 16 days of Terra and Aqua MODIS data at a 30 arc second resolution. Data are temporally weighted to the ninth day of the 16-day acquisition period.

Use Cases

• Derive BRDF/Albedo values for MODIS band 3 by combining the isotropic parameter with volumetric and geometric parameters.
• Apply band-specific quality flags to isolate highest quality full inversion results for surface reflectance analysis.
• Input isotropic parameter data into climate simulation models using the global Climate Modeling Grid (CMG).
• Study daily changes in land surface reflectance properties using the temporally weighted, 16-day composite data.

Strengths

• Daily production provides frequent updates for temporal analysis.
• Global coverage at 30 arc second resolution suitable for climate-scale modeling.
• Data integrates 16 days of Terra and Aqua MODIS observations for robust retrievals.

Limitations

• Each product file contains only one data layer, requiring multiple files for full parameter set.
• Known issues exist, requiring users to consult external assessment websites.
• Specific row count, column details, and sample data are unavailable for evaluation.
