Daily Global Shortwave BRDF Geometric Parameter at 1km Resolution

MCD43D30 Version 6.1 provides the geometric parameter for the Bidirectional Reflectance Distribution Function and Albedo model for the MODIS shortwave broadband. The dataset is produced daily using 16 days of Terra and Aqua MODIS data at 30 arc second (1,000 meter) resolution and covers the entire globe. LPCLOUD generates this Climate Modeling Grid product for use in climate simulation models.

Use Cases

• Derive shortwave broadband albedo values by combining the geometric parameter with isotropic and volumetric parameters from companion datasets.
• Assess surface reflectance anisotropy for climate modeling by analyzing the daily geometric parameter layer.
• Filter data quality for scientific applications using the band-specific quality flags referenced in the user guide.
• Study temporal changes in land surface properties by utilizing the daily product temporally weighted to the ninth day.

Strengths

• Global spatial coverage at 1,000 meter resolution.
• Daily temporal production using 16 days of MODIS data for stability.

Limitations

• Each product file contains only one data layer, requiring multiple files for full parameter set.
• Known issues exist, requiring consultation of the MODIS/VIIRS Land Quality Assessment website.
• Large file sizes are noted, which may impact data handling.
