VNP43D23: VIIRS BRDF Volumetric Parameter for Band M10

Daily global data from 2012 onward, produced using a 16-day rolling window of observations. This dataset provides the volumetric model parameter for the Suomi NPP VIIRS sensor's M10 band (1.61 μm), which is used to derive Bidirectional Reflectance Distribution Function (BRDF) and albedo values. It is formatted on a 30 arc-second Climate Modeling Grid for use in climate simulation models.

Use Cases

• Modeling land surface anisotropy for climate simulations based on the BRDF volumetric parameter.
• Deriving surface albedo values for the 1.61 μm spectral band in conjunction with isotropic and geometric parameters.
• Assessing long-term changes in land surface reflectance using a daily, globally-complete Climate Modeling Grid product.

Strengths

• Provides a specific, foundational model parameter (volumetric) for BRDF/albedo derivation at a 1,000-meter resolution.
• Has a documented, multi-platform presence (Data.gov, NASA Earthdata), indicating established use and validation.
• Covers the entire globe on a Climate Modeling Grid designed for direct use in climate models.

Limitations

• This specific Version 1 product was decommissioned on July 31, 2025, and users are directed to newer versions.
• Metadata for specific column names, row counts, and file sizes is not provided in the available sources.
• The product is noted to be affected by known issues with upstream aerosol flagging, which reduces the number of acceptable observations.
