VNP43D64: Black-Sky Albedo for VIIRS NIR Band

Daily VNP43D64 data is produced using 16 days of VIIRS observations at 30 arc second (1,000 meter) resolution, temporally weighted to the ninth day. This dataset provides black-sky albedo (BSA) for the VIIRS near-infrared broadband (0.865 μm) on a global Climate Modeling Grid (CMG). It is part of a suite of albedo products covering multiple spectral bands and is intended for use in climate simulation models.

Use Cases

• Climate model parameterization based on the global Climate Modeling Grid (CMG) coverage.
• Analysis of land surface reflectance changes using daily, temporally weighted albedo values.
• Studying the anisotropy of surface reflectance using the Bidirectional Reflectance Distribution Function (BRDF) methodology.

Strengths

• Provides daily global coverage at a consistent 30 arc second resolution.
• Includes albedo values for multiple VIIRS spectral bands, including the Day/Night Band (DNB).
• Algorithm improvements include better calibration coefficients and improved geolocation accuracy.

Limitations

• Specific file size, row count, and column details are not provided across platforms.
• The dataset's license is listed as 'other-license-specified' without further details.
• Each VNP43D product contains only one data layer due to large file sizes.
