VJ143D75: White-Sky Albedo for VIIRS Band M11 at 1km Resolution

NOAA-20 VIIRS BRDF/Albedo product VJ143D75 provides daily white-sky albedo values for the M11 band (2.25 μm) at a 30 arc-second (1,000 meter) global resolution. The data are generated using a 16-day temporal window, weighted to the ninth day, and formatted on a Climate Modeling Grid for use in climate simulations. This product is part of a suite that includes albedo for multiple VIIRS spectral bands and the Day/Night Band.

Use Cases

• Parameterizing land surface albedo in climate simulation models based on the Climate Modeling Grid format.
• Analyzing temporal trends in surface reflectance for band M11 (2.25 μm) using the daily, 16-day composite product.
• Comparing white-sky albedo (bihemispherical reflectance) with black-sky albedo for a complete BRDF analysis.
• Incorporating VIIRS-derived albedo, including from the Day/Night Band, into continuity studies with prior MODIS products.

Strengths

• Provides global coverage on a standardized Climate Modeling Grid at 1km resolution.
• Includes algorithmic improvements from the S-NPP VIIRS V002 version, such as enhanced calibration and geolocation.
• Offers daily data production using a consistent 16-day temporal compositing method.

Limitations

• Metadata for row count, file size, and specific columns is unavailable across all platforms.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
• Each product file contains only one data layer, which may increase data management complexity for multi-band analysis.
