MCD43D02: Daily Global BRDF Volumetric Parameter for MODIS Band 1

MCD43D02 Version 6 is a decommissioned daily global dataset of Bidirectional Reflectance Distribution Function (BRDF) volumetric parameters for MODIS band 1. The dataset was produced by NASA using 16 days of Terra and Aqua MODIS observations at a 30 arc second (approximately 1,000 meter) resolution, with data weighted to the ninth day. It is part of a suite of Climate Modeling Grid (CMG) products designed for use in climate simulation models.

Use Cases

• Deriving BRDF/Albedo values for MODIS band 1 based on the volumetric, isotropic, and geometric parameters described.
• Incorporating daily, globally gridded land surface reflectance parameters into climate simulation models.
• Isolating high-quality full inversion results for science applications using the band-specific quality flags mentioned in the user guide.
• Analyzing surface radiative properties over time using the temporally weighted ninth-day data.

Strengths

• Provides data at a consistent 30 arc second (1,000 meter) global Climate Modeling Grid (CMG) resolution.
• Uses 16 days of Terra and Aqua MODIS observations, weighted to a central ninth day for temporal consistency.
• Designed specifically for integration into climate simulation models.

Limitations

• The dataset (Version 6) was decommissioned on July 31, 2023, due to known issues impacting downstream products, particularly over arid bright surfaces.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
• Row count and file size are unknown, which may limit suitability assessment.
