VNP43D09: VIIRS BRDF Geometric Parameter for Band M3

Global coverage is provided by this daily product at 30 arc-second (1,000 meter) resolution. It contains the Bidirectional Reflectance Distribution Function geometric parameter for the VIIRS band M3 (0.488 μm), produced using 16 days of data weighted to the ninth day. This single-layer data is part of a suite designed for climate simulation models.

Use Cases

• Deriving BRDF/Albedo values for VIIRS band M3 based on the geometric parameter combined with isotropic and volumetric parameters.
• Inputting land surface reflectance anisotropy data into global climate simulation models based on the Climate Modeling Grid format.
• Analyzing temporal changes in surface reflectance using daily, temporally weighted data from a 16-day window.
• Assessing land surface radiative properties, including albedo, using the geometric parameter for the 0.488 μm wavelength band.

Strengths

• Provides global spatial coverage via a Climate Modeling Grid (CMG).
• Offers daily temporal resolution with data weighted to a specific day within a 16-day composite.
• Is part of a standardized product suite (VNP43D) with documented methodology and algorithm improvements.

Limitations

• Metadata completeness is low; column names, row counts, and file sizes are unknown across all sources.
• Each product file contains only one data layer, which may limit immediate multi-parameter analysis.
• The dataset has known issues, requiring users to consult an external website for complete information.
