VNP43D67: VIIRS White-Sky Albedo for Band M1 Daily Global 1km

VNP43D67 Version 1 was a daily, global satellite-derived dataset providing white-sky albedo values for the 0.412 μm wavelength (VIIRS band M1) at a 1-kilometer resolution. It was produced by NASA/NOAA using 16 days of Suomi NPP VIIRS observations, temporally weighted to a central date, and formatted for climate simulation models on a Climate Modeling Grid. This specific product was decommissioned on July 31, 2025, with users directed to its Version 2 successors.

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 product.
• Studying aerosol interactions with surface properties, informed by the documented high aerosol flag issue in Collection 1.

Strengths

• Provides global coverage on a Climate Modeling Grid (CMG) designed for direct use in climate models.
• Offers a specific, physically-defined measurement (white-sky albedo) at a consistent 1-kilometer spatial resolution.
• Is part of a cross-platform, well-documented NASA/NOAA product suite with a defined versioning and deprecation policy.

Limitations

• The dataset described (Version 1) is explicitly decommissioned and no longer available for use.
• Metadata for key attributes like row count, file size, and specific column names is unavailable across all sources.
• A known quality issue is noted regarding an abnormally high activation of the high aerosol flag in Collection 1 data.
