VJ143D54: VIIRS Black-Sky Albedo for Band M1 Daily Global Climate Grid

The NOAA-20 VIIRS VJ143D54 product provides daily black-sky albedo values for band M1 (0.412 μm) at a 30 arc-second (1,000 meter) resolution. It is generated using a 16-day temporal window weighted to the ninth day and is formatted on a Climate Modeling Grid covering the entire globe. This dataset is part of a suite that includes albedo for nine moderate resolution bands and the Day/Night Band.

Use Cases

• Climate simulation modeling based on the global Climate Modeling Grid (CMG) coverage.
• Analyzing land surface albedo anisotropy using the Bidirectional Reflectance Distribution Function (BRDF) methodology.
• Monitoring daily surface reflectance changes at 0.412 μm wavelength (Band M1).
• Comparing black-sky albedo (BSA) and white-sky albedo (WSA) values across VIIRS spectral bands.

Strengths

• Provides daily global coverage at a consistent 1,000-meter resolution.
• Includes albedo values for the VIIRS Day/Night Band (DNB), beyond standard moderate resolution bands.
• Algorithm improvements include better calibration coefficients and improved geolocation accuracy for the NOAA-20 mission.

Limitations

• Specific column names and dataset size (rows, file size) are not provided by any source.
• The license is listed as 'other-license-specified' without further details.
• Each product file contains only one data layer due to large file size, which may complicate multi-band analysis.
