VNP43D54: VIIRS Black-Sky Albedo for Band M1 Daily Global Climate Grid

NASA/NOAA Suomi NPP VIIRS data provides daily, global black-sky albedo measurements for the 0.412 μm spectral band at a 1,000-meter resolution. Each daily product synthesizes 16 days of observations, temporally weighted to the ninth day, and is formatted specifically for climate simulation models on a Climate Modeling Grid. This dataset is part of a larger BRDF/Albedo product suite that includes values for nine moderate bands and the Day/Night Band.

Use Cases

• Modeling surface energy budgets based on black-sky albedo (directional hemispherical reflectance) values.
• Analyzing temporal trends in land surface reflectance for band M1 (0.412 μm) from daily, global composites.
• Incorporating albedo parameters into climate simulation models using the Climate Modeling Grid (CMG) format.
• Cross-comparing albedo products across the VIIRS spectral bands (M1-M5, M7, M8, M10, M11) within the VNP43D suite.

Strengths

• Provides global coverage on a Climate Modeling Grid (CMG) designed for climate simulations.
• Offers daily temporal resolution synthesized from a 16-day observation window.
• Maintains a consistent 30 arc-second (1,000 meter) spatial resolution.

Limitations

• The VNP43D54 Version 1 product was decommissioned on July 31, 2025; users are directed to Version 2.
• Metadata for row count, file size, and specific columns is unavailable (listed as 'unknown' or 'None').
• Platform sources list conflicting 'last updated' dates (2026-04-09 and 2025-02-01).
