VJ143D67: White-Sky Albedo for VIIRS Band M1

Daily 30-arc-second (1,000-meter) resolution white-sky albedo data for the 0.412 μm band (M1) is produced from the NOAA-20 VIIRS instrument using a 16-day temporal composite. The product is part of a global Climate Modeling Grid suite providing albedo values for nine moderate-resolution bands and the Day/Night Band. Its primary use is in climate simulation models and land surface studies.

Use Cases

• Parameterizing land surface albedo in climate models based on the Climate Modeling Grid (CMG) format.
• Monitoring temporal changes in surface reflectance for the 0.412 μm wavelength using daily, temporally-weighted composites.
• Comparing white-sky albedo (bihemispherical reflectance) with black-sky albedo for atmospheric correction studies.
• Assessing surface radiative properties for the VIIRS Day/Night Band (DNB) in addition to the standard moderate resolution bands.

Strengths

• Provides global coverage at a consistent 30-arc-second (1,000-meter) spatial resolution.
• Offers daily temporal granularity synthesized from a 16-day observation window for temporal stability.
• Cross-platform presence on NASA Earthdata and Data.gov indicates established importance and accessibility.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided.
• Each product file contains only one data layer due to large file sizes, which may complicate multi-band analysis.
• Known issues exist and require external reference to the MODIS/VIIRS Land Quality Assessment website.
