VNP43D70: VIIRS White-Sky Albedo for Band M4

VNP43D70 Version 1 is a NASA/NOAA Suomi NPP VIIRS data product providing daily white-sky albedo (WSA) for the M4 band (0.555 μm). It is generated using a 16-day rolling window at a 1,000-meter resolution on a global Climate Modeling Grid (CMG). This product was decommissioned on July 31, 2025, and users are directed to Version 2 products.

Use Cases

• Climate model parameterization based on daily, globally-complete albedo data.
• Analysis of land surface reflectance anisotropy using the BRDF/Albedo product suite.
• Monitoring changes in surface albedo over time from the 16-day temporally weighted data.
• Comparative studies using white-sky albedo (WSA) and black-sky albedo (BSA) values across VIIRS bands.

Strengths

• Provides global coverage on a Climate Modeling Grid (CMG) for direct use in models.
• Offers daily data with a consistent 1,000-meter (30 arc-second) spatial resolution.
• Part of a detailed product suite (VNP43D) with documented methodology and Algorithm Theoretical Basis Document (ATBD).

Limitations

• The Version 1 product is decommissioned, indicating it is not the current operational dataset.
• Known issues include an abnormally high activation of the high aerosol flag in Collection 1.
• Key metadata like row count, file size, and specific column names are unavailable across all sources.
