VIIRS VJ143D24: BRDF Geometric Parameter for Band M10

Global daily data provides the Bidirectional Reflectance Distribution Function (BRDF) geometric model parameter for the NOAA-20 VIIRS sensor's M10 band (1.61 μm). This parameter, produced using a 16-day temporal composite at 30 arc-second (1,000 meter) resolution, is part of a suite used to derive surface albedo and reflectance anisotropy. The product is formatted in a Climate Modeling Grid (CMG) for integration into climate simulation models.

Use Cases

• Deriving surface albedo for VIIRS band M10 based on the geometric BRDF parameter.
• Modeling land surface anisotropy in the shortwave infrared (1.61 μm) wavelength.
• Inputting BRDF parameters into global climate simulation models based on the CMG format.
• Analyzing temporal changes in surface reflectance using daily, 16-day composite data.

Strengths

• Provides a specific geometric parameter for a defined spectral band (M10 at 1.61 μm).
• Offers global coverage at a consistent 30 arc-second spatial resolution.
• Includes improvements from the S-NPP VIIRS V002 algorithm, such as better calibration coefficients.

Limitations

• Metadata completeness is low; column names, row counts, and file sizes are unknown.
• Known issues exist and require consultation of an external assessment website.
• Each product file contains only one data layer, which may complicate multi-band analysis.
