MCD43D06: Daily Global BRDF Geometric Parameter for MODIS Band 2 at 1km

MCD43D06 Version 6 was decommissioned on July 31, 2023, with users directed to the newer Version 6.1. This NASA product provides the Bidirectional Reflectance Distribution Function (BRDF) geometric parameter for MODIS band 2, generated daily from 16 days of Terra and Aqua satellite data at a 1,000-meter resolution. The data are temporally weighted to the ninth day of the 16-day period and formatted as a global Climate Modeling Grid (CMG).

Use Cases

• Modeling land surface reflectance for climate simulations based on the daily, global Climate Modeling Grid (CMG) format.
• Deriving albedo values for MODIS band 2 using the geometric parameter in conjunction with the isotropic and volumetric parameters.
• Assessing surface radiative properties over time using data temporally weighted to represent the ninth day of a 16-day period.
• Isolating high-quality full inversion results for scientific applications using the band-specific quality flags mentioned in the user guide.

Strengths

• Provides daily global coverage at a consistent 30 arc second (1,000 meter) spatial resolution.
• Uses 16 days of observations from both Terra and Aqua MODIS sensors, with temporal weighting to improve representativeness.
• Designed specifically for use in climate simulation models as a Climate Modeling Grid (CMG) product.

Limitations

• The dataset description notes known issues in Collection 6, advising users to avoid substantive use and wait for the corrected Collection 6.1 products.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale processing.
