VJ143D02: Volumetric BRDF Parameter for VIIRS Band M1

Daily global data at 30 arc-second (1,000 meter) resolution, produced using a 16-day rolling window weighted to the ninth day. The VJ143D02 product provides the volumetric parameter for the Bidirectional Reflectance Distribution Function (BRDF) and Albedo model for the VIIRS band M1 (0.412 μm). It is part of a Climate Modeling Grid (CMG) suite designed for use in climate simulation models, with each file containing a single data layer.

Use Cases

• Modeling surface albedo for climate simulations based on the volumetric BRDF parameter.
• Analyzing temporal changes in land surface reflectance using the daily, 16-day composite data.
• Integrating VIIRS-derived BRDF parameters into broader Earth system models that use the Climate Modeling Grid format.

Strengths

• Provides global spatial coverage at a consistent 30 arc-second resolution.
• Offers daily temporal granularity, synthesized from a 16-day observation window to reduce noise.
• Part of a multi-platform, standardized product suite (VJ143D01-VJ143D39) indicating established use.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided.
• Each product file contains only one data layer, which may increase complexity for multi-parameter analysis.
• Relies on external documentation (Algorithm Theoretical Basis Document) for full methodological details.
