VNP43D05: BRDF Volumetric Parameter for VIIRS Band M2

VNP43D05 is a decommissioned NASA/NOAA satellite data product providing the volumetric parameter for Bidirectional Reflectance Distribution Function (BRDF) and albedo modeling for VIIRS band M2 (0.445 μm). It is produced daily using a 16-day rolling window at a 30 arc-second (1,000 meter) resolution on a global Climate Modeling Grid. The volumetric parameter, along with isotropic and geometric parameters, is used to derive surface reflectance and albedo values.

Use Cases

• Deriving surface albedo for climate simulation models based on the BRDF model parameters.
• Analyzing temporal changes in land surface reflectance using daily, globally gridded data.
• Studying the anisotropic reflectance properties of surfaces in the blue spectral band (0.445 μm).

Strengths

• Provides a specific BRDF model parameter (volumetric) for a key VIIRS spectral band.
• Offers global coverage at a consistent 1,000-meter resolution on a Climate Modeling Grid.
• Is part of a larger, well-documented product suite (VNP43D) with an Algorithm Theoretical Basis Document.

Limitations

• The Version 1 product was decommissioned on July 31, 2025, limiting access to current data.
• Metadata for row count, file size, and specific columns is unavailable across all sources.
• The product is affected by known issues from upstream data, such as an abnormally high aerosol flag activation.
