VJ143D55: Black-Sky Albedo for VIIRS Band M2 at 1km Resolution

NOAA-20 VIIRS VJ143D55 provides daily black-sky albedo values for the M2 band (0.445 μm) at a 30 arc-second (1,000 meter) global resolution. The data are produced using a 16-day temporal composite weighted to the ninth day and are formatted on a Climate Modeling Grid for climate simulation. This product is part of a larger suite that includes albedo for nine VIIRS moderate resolution bands and the Day/Night Band.

Use Cases

• Modeling surface energy budgets based on black-sky albedo values for a specific spectral band.
• Analyzing temporal trends in land surface reflectance using a daily, 16-day composite product.
• Integrating albedo data into global climate simulation models via the provided Climate Modeling Grid format.
• Comparing albedo properties across different VIIRS spectral bands within the VJ143D product suite.

Strengths

• Provides global coverage on a Climate Modeling Grid designed for climate simulations.
• Offers daily temporal resolution using a consistent 16-day compositing method.
• Includes algorithm improvements such as enhanced calibration and geolocation accuracy from the S-NPP VIIRS V002 baseline.

Limitations

• Each product file contains only a single data layer, which may complicate multi-band analysis.
• Metadata completeness is inconsistent across platforms, with missing column, size, and row information.
• Known issues exist and require external consultation of the MODIS/VIIRS Land Quality Assessment website.
