VJ143D07: VIIRS BRDF Isotropic Parameter for Band M3

Global daily data at 30 arc-second (1,000 meter) resolution provides the isotropic model parameter for the VIIRS Band M3 (0.488 μm). This parameter, part of a suite of three (isotropic, volumetric, geometric), is used to derive Bidirectional Reflectance Distribution Function (BRDF) and albedo values for land surfaces. The product is generated using 16 days of data, temporally weighted to the ninth day, and formatted in a Climate Modeling Grid (CMG) for use in climate simulation models.

Use Cases

• Deriving BRDF and albedo values for VIIRS Band M3 based on the isotropic model parameter.
• Inputting land surface anisotropy data into global climate simulation models based on the Climate Modeling Grid format.
• Analyzing daily changes in surface reflectance properties using the 16-day rolling composite.
• Comparing isotropic parameters across different VIIRS spectral bands (M1-M9, visible, NIR, shortwave, and Day/Night Band).

Strengths

• Provides a specific model parameter (isotropic) for a defined spectral band (M3 at 0.488 μm).
• Offers global coverage at a consistent 30 arc-second spatial resolution.
• Is part of a larger, well-defined product suite (VJ143D01-VJ143D39) with documented methodology and Algorithm Theoretical Basis Document.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• Dataset size and row counts are unknown across all sources.
• License information is inconsistently reported ('other-license-specified' vs 'None').
