VJ143D73: VIIRS White-Sky Albedo for Band M8

NOAA-20 VIIRS VJ143D73 provides daily white-sky albedo values for the VIIRS moderate resolution band M8 (1.240 μm). The data are produced using a 16-day temporal composite at a 30 arc-second (approximately 1 km) resolution, temporally weighted to the ninth day, and formatted in a global Climate Modeling Grid (CMG). This product is part of a suite that includes albedo for nine VIIRS bands and the Day/Night Band.

Use Cases

• Climate model parameterization based on the global Climate Modeling Grid (CMG) format.
• Monitoring land surface reflectance changes using daily composites with a 16-day temporal window.
• Analyzing spectral albedo in the near-infrared (1.240 μm) for vegetation or soil studies.
• Comparing white-sky albedo (bihemispherical reflectance) with black-sky albedo for radiative transfer modeling.

Strengths

• Provides a specific spectral measurement for band M8 at 1.240 μm.
• Offers global coverage at a consistent 30 arc-second (1 km) resolution.
• Includes algorithmic improvements from the S-NPP VIIRS V002 version, such as improved calibration and geolocation.

Limitations

• Metadata for row count, file size, and specific columns is unavailable across all platforms.
• Each large file contains only one data layer, which may limit concurrent analysis of multiple bands.
• The dataset's documentation refers to external sources for known issues and methodology details.
