VJ143D15: VIIRS BRDF Geometric Parameter for Band M5

Global daily data provides the geometric parameter for the Bidirectional Reflectance Distribution Function (BRDF) and Albedo model for NOAA-20 VIIRS band M5 (0.672 μm). The product is generated daily using a 16-day temporal composite weighted to the ninth day and is provided at a 30 arc-second (1,000 meter) resolution on a Climate Modeling Grid. This single-layer file is part of a larger suite of model parameters used to derive surface reflectance and albedo values.

Use Cases

• Deriving surface albedo for climate simulation models based on the BRDF model parameters.
• Analyzing land surface anisotropy and reflectance changes over time using the daily, temporally-weighted product.
• Incorporating VIIRS band M5 (0.672 μm) reflectance data into land quality assessments.
• Studying surface radiative properties using the geometric parameter alongside isotropic and volumetric parameters.

Strengths

• Provides a specific geometric parameter for a single VIIRS spectral band (M5 at 0.672 μm), enabling precise BRDF/albedo derivation.
• Offers global coverage on a Climate Modeling Grid (CMG) at a consistent 30 arc-second resolution.
• Is part of a standardized, multi-platform product suite (VJ143D) with documented methodology and known issue tracking.

Limitations

• The dataset consists of a single data layer per file, which may require combining multiple files for full analysis.
• Metadata completeness is low; specific column names, row counts, and file sizes are not provided.
• The license is listed as 'other-license-specified' without further details.
