VNP43D74: VIIRS/NPP White-Sky Albedo for Band M10

NASA/NOAA Suomi NPP VIIRS BRDF/Albedo product VNP43D74 provides daily white-sky albedo measurements for the 1.61 μm band (M10) at a 30 arc-second (1,000 meter) resolution. The data are produced using a 16-day temporal composite, weighted to the ninth day, and are formatted on a global Climate Modeling Grid for use in climate simulations. This dataset is part of a larger suite that provides albedo values for multiple VIIRS spectral bands.

Use Cases

• Modeling surface energy budgets based on white-sky albedo values for the 1.61 μm shortwave infrared band.
• Monitoring long-term land surface changes using a daily, globally-complete Climate Modeling Grid product.
• Assessing surface anisotropy and radiative properties as part of the broader VIIRS BRDF/Albedo product suite.

Strengths

• Provides daily global coverage at a consistent 1,000-meter spatial resolution.
• Data are part of a sustained NASA/NOAA mission with documented improvements in calibration and geolocation.
• Specifically designed for climate simulation models via its Climate Modeling Grid format.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided by any source.
• Each product file contains only a single data layer, which may require combining multiple files for multi-band analysis.
