MODIS Daily Global BRDF Geometric Parameter for Band 2

MCD43D06 provides the Bidirectional Reflectance Distribution Function (BRDF) geometric model parameter for MODIS band 2, derived from 16 days of Terra and Aqua satellite data at a 30 arc-second (1,000 meter) resolution. This NASA-produced dataset is generated daily, covers the entire globe, and is designed for climate simulation models. It is one of 30 separate files, each containing a single model parameter for a specific spectral band.

Use Cases

• Deriving BRDF and albedo values for MODIS band 2 by combining the geometric parameter with isotropic and volumetric parameters from other files in the MCD43D series.
• Analyzing daily, global land surface anisotropy using the geometric kernel parameter for band 2 reflectance.
• Incorporating temporally weighted, 1km resolution surface reflectance data into climate modeling grids for long-term simulations.
• Assessing land surface changes by utilizing the band-specific quality flags to filter for highest-quality full inversion results.

Strengths

• Provides daily global coverage at a consistent 30 arc-second (1km) Climate Modeling Grid resolution.
• Utilizes data from both Terra and Aqua MODIS sensors, improving temporal compositing over a 16-day window.
• Version 6.1 includes calibration improvements such as updated response-versus-scan angle corrections and crosstalk adjustments for Terra MODIS IR bands.

Limitations

• Specific row/column counts and dataset size are not provided by any source, limiting precise assessment of data volume.
• Each file contains only one data layer (the geometric parameter for a single band), requiring combination with other files for complete analysis.
• Users must consult external resources for known data quality issues and to apply band-specific quality flags for optimal results.
