VJ143D61: Black-Sky Albedo for VIIRS Band M10

NOAA-20 VIIRS VJ143D61 provides daily black-sky albedo (BSA) for the 1.61 μm (M10) band at a 30 arc-second (1,000 meter) global resolution. The product is generated using a 16-day data composite temporally weighted to the ninth day and is formatted on a Climate Modeling Grid (CMG) for climate simulations. This dataset is part of a suite that includes albedo for nine VIIRS moderate bands and the Day/Night Band.

Use Cases

• Modeling surface radiative forcing in climate simulations based on the Climate Modeling Grid (CMG) format.
• Analyzing temporal changes in land surface albedo using the daily, 16-day composite time series.
• Studying the anisotropy of reflectance for the 1.61 μm shortwave infrared band (M10) as described by the BRDF/Albedo model.

Strengths

• Provides global coverage at a consistent 30 arc-second (1,000 meter) spatial resolution.
• Offers daily temporal resolution using a 16-day composite to reduce noise, as explicitly described.
• Cross-platform presence on NASA Earthdata and Data.gov indicates established use and institutional support.

Limitations

• Metadata completeness is medium; specific column names, row counts, and file sizes are not provided.
• Each product file contains only one data layer due to large file sizes, which may complicate multi-band analysis.
• The license is listed as 'other-license-specified' on some platforms but 'None' on others, indicating a potential conflict or lack of clarity.
