VJ143D68: White-Sky Albedo for VIIRS Band M2 Daily Global Climate Grid

VJ143D68 provides daily white-sky albedo values for the VIIRS band M2 (0.445 μm) at a 30 arc-second (1,000 meter) resolution. The data is produced using a 16-day temporal composite weighted to the ninth day and is formatted in a Climate Modeling Grid covering the entire globe. This product is part of a suite that includes albedo 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 reflectance anisotropy using the Bidirectional Reflectance Distribution Function (BRDF) methodology.
• Studying albedo dynamics for the VIIRS Day/Night Band (DNB) included in the product suite.
• Monitoring land surface albedo changes at a 1,000-meter resolution over a 16-day composite period.

Strengths

• Provides a specific spectral measurement for band M2 at 0.445 μm.
• Offers global coverage at a consistent 30 arc-second spatial resolution.
• Includes improvements such as an improved calibration algorithm and better geolocation accuracy from the V002 version.

Limitations

• Column names and dataset size (rows, file size) are not specified in any source.
• License information is inconsistently reported as 'other-license-specified' on one platform and null on others.
• Each product file contains only one data layer, which may limit multi-band analysis within a single file.
