VNP43D69: VIIRS White-Sky Albedo for Band M3 Daily Global Climate Grid

Daily global white-sky albedo data for the VIIRS M3 band (0.488 μm) at 1,000-meter resolution, produced using a 16-day rolling window and temporally weighted to the ninth day. This dataset is part of the NASA/NOAA Suomi NPP VIIRS BRDF/Albedo product suite, formatted in a Climate Modeling Grid for global climate simulations. The VNP43D69 Version 1 product was decommissioned on July 31, 2025, with users directed to newer Version 2 products.

Use Cases

• Modeling surface energy balance in climate simulations based on the provided white-sky albedo values.
• Analyzing temporal changes in land surface reflectance using the daily, 16-day composite data.
• Integrating albedo data for the VIIRS Day/Night Band (DNB) into night-time environmental studies.
• Studying aerosol impacts on surface reflectance, referencing the known issue with high aerosol flag activation.

Strengths

• Provides global coverage at a consistent 30 arc-second (1,000-meter) spatial resolution.
• Offers daily temporal granularity synthesized from a 16-day window for stability.
• Specifically designed for climate simulation models via the Climate Modeling Grid (CMG) format.

Limitations

• The dataset is a decommissioned Version 1 product, indicating it is not the current standard.
• Metadata completeness is low: column names, row counts, and file sizes are unknown across all sources.
• Each file contains only one data layer due to large file sizes, which may increase data management complexity.
