VNP43D47: VIIRS BRDF/Albedo Valid Observations for Band M7

NASA/NOAA Suomi NPP VIIRS VNP43D47 provides a daily global layer of valid observation quality for band M7, derived from a 16-day rolling window at 30 arc-second (1,000 meter) resolution. The data are temporally weighted to the ninth day and formatted on a Climate Modeling Grid for use in climate simulation models. This product is part of a suite detailing BRDF, albedo, quality, and uncertainty parameters for multiple VIIRS bands.

Use Cases

• Validating surface reflectance retrievals for VIIRS band M7 based on the 16-day observation quality layer.
• Assessing data quality for downstream climate modeling based on the Climate Modeling Grid (CMG) format.
• Monitoring temporal changes in land surface properties using the daily, temporally-weighted product.
• Improving aerosol retrieval algorithms over bright surfaces using corrections referenced in the product's known issues.

Strengths

• Provides daily global coverage at a consistent 30 arc-second spatial resolution.
• Incorporates improvements from a specific version update, including better calibration coefficients and geolocation accuracy.
• Designed specifically for climate simulation models via the Climate Modeling Grid format.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided by any source.
• Relies on a 16-day composite window, which may smooth over rapid surface changes.
• Known issues exist, requiring users to consult an external quality assessment website for complete information.
