VNP43D58: VIIRS Black-Sky Albedo for Band M5 Daily Global Climate Grid

VNP43D58 provides daily black-sky albedo values for the VIIRS M5 band at 0.672 μm, produced using a 16-day rolling window at a 30 arc-second (1,000 meter) resolution. The data are temporally weighted to the ninth day and formatted in a global Climate Modeling Grid for use in climate simulations. This product is part of the VNP43D BRDF/Albedo suite and was decommissioned in July 2025, with users directed to newer Version 2 data.

Use Cases

• Modeling surface energy balance in climate simulations based on the global Climate Modeling Grid (CMG) format.
• Analyzing temporal trends in land surface reflectance using the daily, 16-day composite data product.
• Studying directional hemispherical reflectance (black-sky albedo) as a function of solar zenith angle for band M5.
• Cross-comparing albedo values across VIIRS moderate resolution bands within the VNP43D product suite.

Strengths

• Provides global spatial coverage in a Climate Modeling Grid designed for climate simulation models.
• Offers a consistent daily temporal product with a 16-day composite window for temporal smoothing.
• Delivers data at a specific 30 arc-second (approximately 1,000 meter) spatial resolution.

Limitations

• The dataset is decommissioned (as of July 31, 2025), indicating it is not the current operational version.
• Metadata on row count, file size, and specific columns is unavailable across all sources.
• A known issue with abnormally high activation of the high aerosol flag is noted for Collection 1 data.
