VNP43D10: VIIRS BRDF Isotropic Parameter for Band M4

VNP43D10 provides the isotropic parameter for the Bidirectional Reflectance Distribution Function (BRDF) model for VIIRS band M4 (0.555 μm) at a 30 arc second (1,000 meter) resolution. This daily product is generated using a 16-day temporal window, weighted to the ninth day, and is formatted on a global Climate Modeling Grid (CMG). The isotropic parameter, combined with volumetric and geometric parameters, is used to derive BRDF and albedo values for the green wavelength band.

Use Cases

• Modeling land surface albedo for climate simulations based on the global Climate Modeling Grid (CMG) format.
• Analyzing surface anisotropy and reflectance properties using the BRDF isotropic parameter for the 0.555 μm wavelength.
• Integrating daily, temporally smoothed surface reflectance data into time-series analyses of vegetation or land cover.
• Assessing data quality impacts from known issues with upstream aerosol flags in Collection 1 VNP09 products.

Strengths

• Provides global coverage on a Climate Modeling Grid designed for climate models.
• Offers daily data with a 16-day temporal compositing window to reduce noise.
• Delivers data at a consistent 1,000-meter spatial resolution.

Limitations

• This Version 1 product was officially decommissioned on July 31, 2025, limiting its use for current analysis.
• Metadata on specific column names, row counts, and file sizes is unavailable across all sources.
• Known data quality issues exist due to the high activation of an aerosol flag in an upstream product.
