VNP43D68: VIIRS White-Sky Albedo for Band M2, Daily Global 1km

Global daily white-sky albedo data at 1,000-meter resolution, derived from the Suomi NPP VIIRS sensor for the M2 band (0.445 μm). The dataset is part of a BRDF/Albedo product suite, produced daily using a 16-day temporal window weighted to the ninth day and formatted on a Climate Modeling Grid. It is designed for climate simulation models and surface radiative property studies.

Use Cases

• Modeling surface radiative forcing in climate simulations based on the global Climate Modeling Grid (CMG) structure.
• Analyzing temporal trends in land surface albedo using the daily, 16-day composite data.
• Studying spectral surface properties for the VIIRS M2 band (0.445 μm) as part of broader albedo product suites.

Strengths

• Provides global spatial coverage on a standardized Climate Modeling Grid (CMG).
• Offers daily temporal resolution synthesized from a 16-day observation window.
• Maintained by a authoritative source, the National Aeronautics and Space Administration.

Limitations

• This Version 1 product was officially decommissioned on July 31, 2025, limiting its use for current analyses.
• Metadata for specific column names, row counts, and file sizes is unavailable across all sources.
• A known issue with abnormally high activation of a high aerosol flag is noted for Collection 1 data.
