VNP43D48: VIIRS Band M8 Valid Observation Quality for Global BRDF/Albedo

NASA/NOAA Suomi NPP VIIRS VNP43D48 Version 1 was a daily, global climate modeling grid product providing the valid observation quality layer for band M8, derived from a 16-day rolling window at 30 arc-second (1,000 meter) resolution. This dataset was part of the BRDF/Albedo product suite designed for characterizing surface anisotropy and radiative properties. The product was officially decommissioned on July 31, 2025, with users directed to Version 2 successors.

Use Cases

• Assessing input data quality for BRDF model inversions based on the valid observation layer for VIIRS band M8.
• Monitoring temporal consistency of surface reflectance observations over a 16-day period for climate studies.
• Identifying regions potentially affected by known aerosol flag issues in Collection 1 data over arid, bright surfaces.
• Supporting global climate simulation models with pre-processed, spatially complete CMG data on surface radiative properties.

Strengths

• Provides global coverage on a Climate Modeling Grid (CMG) for direct use in climate models.
• Offers a specific data layer (valid observation quality) for a key VIIRS spectral band (M8) within a well-documented processing chain.
• Data is produced daily using a 16-day temporal composite, weighting observations to the ninth day to reduce gaps.

Limitations

• This Version 1 product is decommissioned (as of July 31, 2025) and should not be used for new work.
• Known data quality issues exist due to high aerosol flag activation in upstream Collection 1 products, reducing high-quality BRDF inversions, especially over bright surfaces.
• Critical metadata (column names, row counts, file size) is unavailable across all platform entries.
