VJ143D60: Black-Sky Albedo for VIIRS Band M8 Daily Global 1km Grid

Daily 1,000-meter resolution black-sky albedo data for the VIIRS M8 band (1.240 μm) is produced using a 16-day rolling composite, temporally weighted to the ninth day. This single-layer product is part of a global Climate Modeling Grid suite providing albedo values for nine VIIRS bands and the Day/Night Band. The dataset is designed for climate simulation models and follows the methodology of the VJ143MA3 product.

Use Cases

• Modeling surface radiative forcing in climate simulations based on the global Climate Modeling Grid (CMG) structure.
• Analyzing temporal trends in land surface albedo using the daily, 16-day composite time series.
• Integrating band-specific black-sky albedo (BSA) for the 1.240 μm wavelength into broader spectral albedo studies.
• Assessing surface anisotropy and reflectance properties for the VIIRS Day/Night Band, which is included in the product suite.

Strengths

• Provides global coverage at a consistent 30 arc-second (approximately 1km) spatial resolution.
• Incorporates algorithmic improvements from the S-NPP VIIRS V002 version, including better calibration and geolocation accuracy.
• Is part of a cross-platform, authoritative data product maintained by NASA.

Limitations

• Metadata completeness is medium; specific column names, row counts, and file sizes are not provided by any source.
• Each product file contains only one data layer due to large file sizes, which may complicate multi-band analysis.
• One source lists a 'last updated' date in the future (2026-04-09), indicating a potential metadata conflict or error.
