VJ143D63: NOAA-20 VIIRS Black-Sky Albedo for Visible Band

NOAA-20 VIIRS BRDF/Albedo Black-Sky Albedo for Band VIS (VJ143D63) is a daily global dataset produced using 16 days of data at 30 arc-second (1,000 meter) resolution. It provides black-sky albedo values for the VIIRS visible broadband (0.64 μm) on a Climate Modeling Grid (CMG) for use in climate simulation models. The product suite includes albedo for multiple spectral bands and the Day/Night Band.

Use Cases

• Climate model parameterization based on the global Climate Modeling Grid (CMG) coverage.
• Land surface albedo trend analysis based on daily, temporally-weighted data.
• Surface radiative property studies based on black-sky albedo values for the visible broadband (0.64 μm).
• Validation of surface reflectance models using the provided BRDF/albedo product suite.

Strengths

• Provides daily global coverage at 30 arc-second (1,000 meter) resolution.
• Includes albedo values for the VIIRS Day/Night Band (DNB), beyond standard spectral bands.
• Data are temporally weighted using 16 days of observations to the ninth day.

Limitations

• Column names and exact data structure are not specified in the provided metadata.
• File sizes are described as large, with each product containing just one data layer.
• The dataset's license is listed as 'other-license-specified' without further detail.
