VNP43D49: VIIRS/NPP Valid Observation Quality for Band M10

Global daily satellite data provides a valid observation quality layer for VIIRS band M10, derived from a 16-day rolling window at 1,000-meter resolution. This product is part of a suite designed for climate simulation models, focusing on surface anisotropy and albedo. The dataset is temporally weighted to the ninth day of the retrieval period and is provided on a Climate Modeling Grid covering the entire globe.

Use Cases

• Assessing input data quality for BRDF/albedo model inversions based on the valid observation layer.
• Monitoring temporal changes in surface observation availability for climate modeling grids.
• Identifying regions potentially affected by high aerosol flags in upstream Collection 1 products.

Strengths

• Provides global coverage on a Climate Modeling Grid (CMG) at 30 arc-second (1,000m) resolution.
• Offers daily production using a 16-day data window, temporally weighted for stability.
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and official provenance.

Limitations

• The Version 1 product was decommissioned on July 31, 2025, directing users to newer versions.
• Metadata for specific columns, row counts, and file sizes is unavailable across all sources.
• A known issue with high aerosol flag activation in upstream data reduces high-quality BRDF inversions, especially over arid bright surfaces.
