VNP43D46: VIIRS BRDF/Albedo Valid Observation Quality for Band M5

NASA/NOAA's Suomi NPP VIIRS VNP43D46 product provides a daily global layer of valid observation quality for band M5, derived from a 16-day rolling window. The data is produced at a 30 arc-second (1,000 meter) resolution on a Climate Modeling Grid for use in climate simulations. This Version 1 product was decommissioned on July 31, 2025, with users directed to updated Version 2 products.

Use Cases

• Assessing input data quality for BRDF and albedo model inversions based on the valid observation layer.
• Monitoring temporal changes in surface observation availability for climate trend analysis based on the 16-day rolling composite.
• Filtering low-quality observations in arid, bright regions where known aerosol flag issues affect downstream products.
• Integrating quality-controlled land surface data into global climate simulation models based on the Climate Modeling Grid format.

Strengths

• Provides a specific quality layer for VIIRS band M5, supporting detailed spectral analysis.
• Offers daily global coverage at a consistent 1,000-meter resolution on a Climate Modeling Grid.
• Data synthesis uses a 16-day temporal window weighted to the ninth day, balancing recency with observational stability.

Limitations

• The dataset is deprecated; Version 1 was decommissioned on July 31, 2025.
• Known issues with high aerosol flag activation in source data reduce high-quality BRDF inversions, especially over bright surfaces.
• Critical metadata like column names, row counts, and specific license terms are unavailable across all sources.
