VNP43D14: VIIRS BRDF Volumetric Parameter for Band M5

NASA/NOAA Suomi NPP VIIRS BRDF/Albedo Model Parameter 2 Band M5 product (VNP43D14) provides the volumetric parameter for deriving surface reflectance anisotropy and albedo. It is produced daily at 30 arc-second (1,000 meter) global resolution, using a 16-day temporal window weighted to the ninth day. This data is part of a Climate Modeling Grid (CMG) suite designed for climate simulation models.

Use Cases

• Deriving land surface albedo for climate models based on the BRDF volumetric parameter for VIIRS band M5 (0.672 μm).
• Analyzing temporal changes in surface anisotropy using the daily, 16-day composite data product.
• Inputting BRDF parameters into radiative transfer models for atmospheric correction studies.
• Global-scale land surface monitoring within a Climate Modeling Grid (CMG) framework.

Strengths

• Provides a specific, single BRDF model parameter (volumetric) for a key VIIRS spectral band (M5 at 0.672 μm).
• Offers global, daily coverage at a consistent 30 arc-second (1,000 meter) spatial resolution.
• Part of a systematically produced, multi-parameter suite (VNP43D01-VNP43D39) for comprehensive BRDF/albedo modeling.

Limitations

• The VNP43D14 Version 1 product is explicitly decommissioned as of July 31, 2025, directing users to newer versions.
• Known data quality issues exist, such as reduced input observations due to an abnormally high aerosol flag in upstream Collection 1 products.
• Metadata on specific columns, row counts, and file sizes is unavailable across all sources.
