VNP43D10: Daily Global BRDF Isotropic Parameter for VIIRS Band M4

Daily data produced using 16 days of observations, temporally weighted to the ninth day, at a 30 arc second (1,000 meter) resolution. The dataset provides the isotropic model parameter for the VIIRS band M4 (0.555 μm), which is part of a global Climate Modeling Grid (CMG) suite used to derive Bidirectional Reflectance Distribution Function (BRDF) and albedo values. It is generated by NASA/NOAA from the Suomi NPP satellite's VIIRS instrument.

Use Cases

• Deriving land surface albedo for climate models based on the BRDF isotropic, volumetric, and geometric parameters.
• Analyzing temporal changes in surface reflectance anisotropy using the daily, globally gridded 30 arc-second data.
• Calibrating or validating other satellite-derived reflectance products using the VIIRS M4 band (0.555 μm) parameter.
• Studying vegetation dynamics and land cover change through modeled surface reflectance properties.

Strengths

• Provides global coverage in a Climate Modeling Grid (CMG) format designed for climate simulation models.
• Offers daily temporal resolution synthesized from 16 days of data, balancing noise reduction with recent observations.
• Part of a consistently processed and documented product suite (VNP43D) from the NASA/NOAA Suomi NPP mission.

Limitations

• Metadata completeness is low: specific column names, row counts, and file sizes are not provided on any platform.
• Each file contains only one data layer, requiring users to combine multiple files (VNP43D01-VNP43D39) for a full parameter set.
• Known issues exist, requiring users to consult an external Land Quality Assessment website for complete information.
