VNP43D14: BRDF Volumetric Parameter for VIIRS Band M5

VNP43D14 is a daily global dataset containing the volumetric model parameter for the Bidirectional Reflectance Distribution Function (BRDF) and Albedo derived from the VIIRS instrument on the Suomi NPP satellite. It is produced using a 16-day rolling window of data at a 30 arc-second (1,000 meter) resolution and is temporally weighted to the ninth day. The data are formatted on a Climate Modeling Grid (CMG) covering the entire globe for use in climate simulation models.

Use Cases

• Modeling surface albedo for climate simulations based on the global Climate Modeling Grid.
• Analyzing land surface anisotropy and reflectance changes over time using the daily, 16-day composite data.
• Deriving BRDF/Albedo values for VIIRS band M5 (0.672 μm) using the volumetric parameter alongside isotropic and geometric parameters.
• Assessing surface radiative properties for specific geographic regions using the 30 arc-second resolution data.

Strengths

• Provides a specific volumetric BRDF parameter for VIIRS band M5 (0.672 μm) at a 30 arc-second (1,000 meter) resolution.
• Offers daily global coverage on a Climate Modeling Grid designed for climate simulation models.
• Incorporates improvements from a previous version, including an improved calibration algorithm and better geolocation accuracy.

Limitations

• Column names and exact data structure are not provided in the source metadata.
• The dataset size and row count are unknown.
• Each product file contains only one data layer due to large file sizes, which may require managing multiple files for a complete analysis.
