VNP43D24: VIIRS BRDF Geometric Parameter for Band M10

VNP43D24 provides the Bidirectional Reflectance Distribution Function geometric parameter for VIIRS band M10 (1.61 μm) at 30 arc second (1,000 meter) resolution. This daily product synthesizes 16 days of data, temporally weighted to the ninth day, and is part of a global Climate Modeling Grid suite used for climate simulation. The geometric parameter, along with isotropic and volumetric parameters, is used to derive BRDF and albedo values for the specific spectral band.

Use Cases

• Deriving land surface albedo for climate models based on the geometric BRDF parameter.
• Analyzing surface anisotropy and reflectance patterns in the 1.61 μm spectral band.
• Inputting pre-calculated BRDF parameters into radiative transfer models for the VIIRS instrument.
• Monitoring long-term changes in land surface properties using a daily, temporally composited product.

Strengths

• Provides a specific, single-layer geometric parameter for VIIRS band M10 at a consistent 30 arc second global resolution.
• Incorporates improvements from a previous version, including a better calibration algorithm and corrected geolocation accuracy.
• Is part of a standardized, multi-platform product suite (VNP43D) designed explicitly for climate modeling grids.

Limitations

• Column names and specific data structure are unknown from the provided metadata.
• The dataset's size and row count are unspecified across all sources.
• License information is inconsistently reported as 'other-license-specified' on datagov but 'None' on nasa_earthdata.
