VNP43D25: VIIRS/NPP BRDF Isotropic Parameter for Band M11

Daily global data produced using 16 days of observations at 30 arc second (1,000 meter) resolution, temporally weighted to the ninth day. The VNP43D25 product provides the isotropic parameter for the VIIRS band M11 (2.25 μm), which is part of a suite of BRDF and albedo model parameters stored on a Climate Modeling Grid for global climate simulation. This parameter, along with volumetric and geometric counterparts, is used to derive BRDF/Albedo values for the specific spectral band.

Use Cases

• Climate simulation modeling based on global, gridded BRDF/albedo parameters.
• Deriving BRDF/Albedo values for VIIRS band M11 using the isotropic, volumetric, and geometric parameters.
• Analyzing temporal changes in surface reflectance anisotropy from daily, 16-day composite data.
• Studying land surface albedo at a 1km resolution for climate and energy balance research.

Strengths

• Provides a specific model parameter (isotropic) for a defined spectral band (M11 at 2.25 μm).
• Offers global coverage on a Climate Modeling Grid (CMG) at 30 arc second resolution.
• Data is produced daily using a 16-day composite, offering a temporally smoothed product.

Limitations

• Each VNP43D product contains only one data layer due to large file size, requiring multiple files for full analysis.
• Metadata completeness is low; column names, row counts, and exact author are unknown.
• Known issues exist, requiring users to consult an external website for complete information.
