Daily Global BRDF Isotropic Parameter for MODIS Band 6

MCD43D16 Version 6.1 provides the isotropic parameter for Bidirectional Reflectance Distribution Function and Albedo modeling for MODIS band 6. Data are produced daily at 30 arc second resolution using 16 days of Terra and Aqua MODIS observations, temporally weighted to the ninth day. The dataset is generated by LPCLOUD for use in global climate simulation models.

Use Cases

• Calculate surface albedo for MODIS band 6 by combining the isotropic parameter with volumetric and geometric parameters.
• Assess daily changes in land surface reflectance properties using the temporally weighted parameter data.
• Integrate the 30 arc second isotropic parameter into global climate simulation grids for radiative forcing studies.
• Filter data quality for scientific applications using the band-specific quality flags referenced in the user guide.

Strengths

• Daily production provides frequent updates for temporal analysis.
• 30 arc second (1,000 meter) resolution offers detailed global coverage.
• Data integrates 16 days of MODIS observations from both Terra and Aqua satellites for robust inversions.

Limitations

• Each product file contains only one data layer, requiring multiple files for full parameter sets.
• Known issues exist, requiring users to consult external quality assessment websites.
• The large file size per single layer may complicate data management.
