VNP43D32: VIIRS NIR BRDF Volumetric Parameter Daily Global

30 arc second (1,000 meter) resolution data provides the volumetric parameter for the VIIRS NIR broadband (0.865 μm) used to derive Bidirectional Reflectance Distribution Function (BRDF) and albedo values. This product is generated daily using a 16-day temporal composite, weighted to the ninth day, and is formatted in a Climate Modeling Grid (CMG) covering the entire globe. Details regarding methodology are available on the VNP43MA1 product page and in the Algorithm Theoretical Basis Document.

Use Cases

• Climate simulation modeling based on the Climate Modeling Grid (CMG) format.
• Deriving BRDF/Albedo values for the VIIRS NIR broadband based on the volumetric parameter combined with isotropic and geometric parameters.
• Analyzing land surface radiative properties over time based on the daily, 16-day composite temporal weighting.
• Studying surface anisotropy and reflectance in the near-infrared spectrum based on the 0.865 μm band parameter.

Strengths

• Provides global coverage at a consistent 30 arc second (1,000 meter) spatial resolution.
• Data is produced daily using a 16-day temporal composite, offering a balance between temporal frequency and data stability.
• The product suite includes model parameters for the VIIRS Day/Night Band (DNB), expanding its utility.

Limitations

• Column names and exact data structure are unknown from all platform sources.
• Specific row counts, file sizes, and detailed license terms are not provided.
• Each VNP43D product contains just one data layer due to large file size, which may complicate multi-parameter analysis.
