VNP43D86: VIIRS Nadir-Adjusted Surface Reflectance for Band M8

Global daily Nadir BRDF-Adjusted Reflectance (NBAR) data at a 1,000-meter resolution, processed for the VIIRS M8 band (1.240 μm). This dataset is part of a climate modeling grid product suite, generated daily using a 16-day temporal composite weighted to the ninth day. It is designed for modeling surface radiative properties but has been decommissioned in favor of a newer version.

Use Cases

• Modeling surface albedo and anisotropy in climate simulations based on the Climate Modeling Grid (CMG) format.
• Analyzing temporal trends in surface reflectance using the daily, 16-day composite data product.
• Correcting for view-angle effects in satellite imagery to standardize reflectance values to a nadir view at solar noon.

Strengths

• Provides global spatial coverage at a consistent 30 arc-second (1,000 meter) resolution.
• Data is produced daily using a 16-day temporal composite, offering regular global snapshots.
• Cross-platform presence on NASA Earthdata and Data.gov signals its established use in the scientific community.

Limitations

• This Version 1 product was decommissioned on July 31, 2025, and is no longer current.
• Known issues include reduced input observations due to high aerosol flag activation in upstream data, potentially affecting surface anisotropy characterization.
• Metadata for size, row count, and specific columns is unavailable across all sources.
