VNP43MA3: VIIRS/NPP Daily Albedo at 1km Resolution

36 Science Dataset layers provide black-sky and white-sky albedo values at 1 kilometer resolution for nine VIIRS moderate bands (M1-M5, M7-M). The product is generated daily using a 16-day rolling window of VIIRS data, weighted to the ninth day, and employs the RossThick/Li-Sparse-Reciprocal BRDF model to correct for surface anisotropic effects. It is part of a suite designed to continue the MODIS BRDF/Albedo data record.

Use Cases

• Modeling surface energy balance based on daily, 1km-resolution albedo values.
• Continuity studies of land surface properties using the VIIRS successor to MODIS BRDF/Albedo products.
• Estimating instantaneous 'blue-sky' albedo by applying a polynomial to the provided black-sky and white-sky albedo layers.
• Analyzing surface anisotropy and directional reflectance effects using the underlying RTLSR BRDF model parameters.

Strengths

• Provides a specific 36 Science Dataset layers for detailed analysis.
• Uses a sophisticated, documented RTLSR kernel-driven BRDF model for atmospheric correction.
• Promotes continuity with the established MODIS BRDF/Albedo product suite.

Limitations

• The Version 1 product was explicitly decommissioned on July 31, 2025, limiting its use for current analysis.
• Key metadata such as row count, file size, and specific column names are not provided across sources.
• Spatial resolution is fixed at 1km, which may be coarse for localized studies.
