VJ143D38: BRDF Volumetric Parameter for VIIRS Day/Night Band

The NOAA-20 VIIRS BRDF/Albedo Model Parameter 2 Day/Night Band product (VJ143D38) provides the volumetric parameter for the VIIRS Day/Night Band (0.7 μm) used to derive surface reflectance and albedo. It is produced daily at 30 arc-second (1,000 meter) resolution, using 16 days of temporally weighted data on a global Climate Modeling Grid. This volumetric parameter, alongside isotropic and geometric parameters, models the Bidirectional Reflectance Distribution Function for the DNB.

Use Cases

• Deriving BRDF/Albedo values for the VIIRS Day/Night Band based on volumetric, isotropic, and geometric parameters.
• Climate simulation modeling using global, daily surface reflectance data on a Climate Modeling Grid.
• Analyzing surface anisotropy and reflectance properties at a 1,000-meter resolution.
• Monitoring land surface radiative changes over time using a 16-day composite weighted to the ninth day.

Strengths

• Provides a specific model parameter (volumetric) for the VIIRS Day/Night Band, a feature not included in the base VJ143MA1 product.
• Offers global coverage on a Climate Modeling Grid designed for climate simulation models.
• Has a daily production cycle with a consistent 30 arc-second spatial resolution.

Limitations

• Metadata completeness is low: column names, dataset size, row counts, and author information are unknown across all platforms.
• The dataset is part of a large product suite where each file contains only one data layer, complicating holistic analysis.
• Known issues exist, requiring users to consult an external website for complete information.
