MODIS BRDF Volumetric Parameter for Visible Broadband Daily Global Data

Daily volumetric parameter data for the visible broadband derived from Terra and Aqua MODIS observations. The dataset is produced daily using a 16-day temporal window and is provided at a 30 arc-second (1,000 meter) resolution global Climate Modeling Grid. It is generated by LPCLOUD as part of NASA's MODIS Version 6.1 product suite.

Use Cases

• Model land surface albedo by combining the volumetric parameter with isotropic and geometric parameters for the visible broadband.
• Analyze daily surface reflectance dynamics using the volumetric parameter layer for the visible band.
• Assess BRDF model quality for climate simulations by applying the band-specific quality flags described in the User Guide.
• Integrate the 30 arc-second CMG volumetric parameter into global climate models for surface energy balance calculations.

Strengths

• Daily temporal resolution using a 16-day data window for stability.
• Global spatial coverage on a Climate Modeling Grid at 30 arc-second resolution.
• Product is part of the Version 6.1 MODIS suite with documented user guidance.

Limitations

• Each product file contains only one data layer, requiring multiple files for full parameter set.
• Users must apply quality flags to isolate high-quality full inversion results.
• Known issues are documented externally and require manual review.
