VNP43D17: BRDF Volumetric Parameter for VIIRS Band M7

NASA/NOAA Suomi NPP's VNP43D17 product provides the volumetric parameter for the Bidirectional Reflectance Distribution Function (BRDF) model for VIIRS band M7 (0.865 μm). This daily, global dataset is generated at 30 arc-second (1,000 meter) resolution using a 16-day temporal composite weighted to the ninth day. It is part of a suite designed for climate simulation models, covering the entire globe on a Climate Modeling Grid.

Use Cases

• Deriving BRDF/Albedo values for VIIRS band M7 based on the volumetric parameter combined with isotropic and geometric parameters.
• Inputting land surface reflectance characteristics into global climate simulation models based on the Climate Modeling Grid (CMG) format.
• Analyzing temporal changes in surface anisotropy using the daily product with a 16-day composite window.
• Studying near-infrared (0.865 μm) land surface properties for applications in vegetation monitoring or land cover change.

Strengths

• Provides a single, focused data layer (the volumetric parameter for band M7) optimized for use in large-scale climate models.
• Offers global coverage at a consistent 30 arc-second (1,000 meter) resolution on a Climate Modeling Grid.
• Incorporates improvements from a previous version, including a better calibration algorithm and enhanced geolocation accuracy.

Limitations

• Column names and detailed data structure are not provided in any source description.
• The dataset's size and row count are unknown across all platforms.
• Known issues exist, requiring users to consult an external website for complete information.
