VJ143D69: White-Sky Albedo for VIIRS Band M3

NOAA-20 VIIRS VJ143D69 provides daily white-sky albedo for the 0.488 μm (M3) band, derived from 16 days of data weighted to the ninth day. The product is generated at a 30 arc-second (1,000 meter) resolution on a global Climate Modeling Grid. It is part of a suite offering 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) coverage.
• Analysis of surface reflectance anisotropy using the bidirectional reflectance distribution function (BRDF) methodology.
• Monitoring land surface albedo changes over time using the daily, temporally-weighted product.
• Comparative studies of albedo across spectral bands using the suite of related VJ143D products.

Strengths

• Provides a specific spectral measurement (white-sky albedo for band M3 at 0.488 μm).
• Offers global coverage on a Climate Modeling Grid designed for simulation models.
• Incorporates algorithm improvements from the S-NPP VIIRS V002 version, including improved calibration and geolocation.
• Is part of a multi-platform dataset, indicating established use and validation.

Limitations

• Column names and exact data structure are not provided in the source metadata.
• File size is described as large, with each product containing only one data layer, which may complicate multi-band analysis.
• Metadata for size, row count, and author is missing or inconsistent across platforms.
