VJ143D26: VIIRS BRDF Volumetric Parameter for Band M11

Daily VJ143D26 data is produced using 16 days of observations at a 30 arc second (1,000 meter) resolution. This product provides the volumetric model parameter for VIIRS band M11 (2.25 μm), which is used alongside isotropic and geometric parameters to derive Bidirectional Reflectance Distribution Function (BRDF) and albedo values. It is part of a global Climate Modeling Grid (CMG) suite designed for climate simulation models.

Use Cases

• Deriving BRDF and albedo values for VIIRS band M11 based on the volumetric parameter.
• Inputting daily, temporally-weighted surface reflectance data into global climate simulation models.
• Analyzing land surface anisotropy and reflectance changes over time using the 16-day composite window.

Strengths

• Provides a specific volumetric parameter for VIIRS band M11 (2.25 μm) at a 1,000-meter resolution.
• Part of a globally comprehensive Climate Modeling Grid (CMG) suite covering the entire Earth.
• Incorporates improvements from the S-NPP VIIRS V002 algorithm, including better calibration coefficients.

Limitations

• Column names are unknown across all platforms, limiting precise understanding of data structure.
• File size is described as large, with each product containing only one data layer, which may complicate handling.
• Metadata completeness varies; some platform entries lack size, row count, author, and license details.
