VNP43D56: VIIRS Black-Sky Albedo for Band M3 Daily Global 1km

NASA/NOAA Suomi NPP VIIRS VNP43D56 Version 1 provided daily global black-sky albedo (directional hemispherical reflectance) for the M3 band (0.488 μm) at 30 arc-second (1,000 meter) resolution. The product was generated using a 16-day temporal composite, weighted to the ninth day, and formatted in a Climate Modeling Grid (CMG) for climate simulation models. This dataset was decommissioned on July 31, 2025, with users directed to the Version 2 products.

Use Cases

• Modeling surface energy balance based on black-sky albedo values for the 0.488 μm wavelength.
• Analyzing temporal trends in land surface reflectance using a daily 16-day composite product.
• Inputting gridded albedo data into climate simulation models based on the global Climate Modeling Grid format.
• Studying the bidirectional reflectance distribution function (BRDF) for the VIIRS M3 band.

Strengths

• Provides a specific geophysical parameter (black-sky albedo) for a defined spectral band (M3 at 0.488 μm).
• Offers global spatial coverage in a standardized Climate Modeling Grid (CMG) format.
• Features a documented temporal compositing method (daily product using 16 days of data, weighted to the ninth day).

Limitations

• Dataset is deprecated (decommissioned July 31, 2025), limiting its utility for current work.
• Column names and specific data structure are unknown from the provided metadata.
• Metadata conflicts on last updated date (2026-04-09 vs. 2025-02-01).
