VNP43D54: VIIRS Black-Sky Albedo for Band M1

NASA/NOAA's Suomi NPP VIIRS VNP43D54 dataset provides daily black-sky albedo (BSA) for the VIIRS M1 band (0.412 μm). It is produced using 16 days of data at 30 arc-second (1,000 meter) resolution, temporally weighted to the ninth day, and formatted in a global Climate Modeling Grid (CMG). The product suite includes albedo values for nine VIIRS moderate resolution bands and the Day/Night Band.

Use Cases

• Climate simulation modeling based on the global Climate Modeling Grid (CMG) format.
• Analyzing surface radiative properties based on black-sky albedo (BSA) values for specific spectral bands.
• Monitoring land surface changes over time based on daily production using a 16-day rolling window.
• Comparing albedo under different atmospheric conditions based on the distinction between black-sky (direct) and white-sky (diffuse) albedo.

Strengths

• Provides global coverage at a consistent 30 arc-second (1,000 meter) resolution.
• Offers daily temporal updates using a 16-day data composite, improving temporal consistency.
• Includes albedo for the VIIRS Day/Night Band (DNB), expanding beyond standard moderate resolution bands.

Limitations

• Metadata completeness is low: column names, row counts, and file sizes are unknown across all sources.
• Each VNP43D product contains only one data layer, which may limit simultaneous multi-band analysis.
• The license is specified as 'other-license-specified' without further detail.
