MCD43D38: Daily Global BRDF/Albedo Quality Data for MODIS Band 6

MCD43D38 Version 6.1 is a NASA-produced daily global dataset providing quality information for the Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) product. It is generated using 16 days of Terra and Aqua MODIS data at a 30 arc second (1,000 meter) resolution, temporally weighted to the ninth day. This Climate Modeling Grid (CMG) product is intended for use in climate simulation models.

Use Cases

• Filtering high-quality BRDF/Albedo inversion results based on the band-specific quality flags described in the user guide.
• Assessing observation coverage and reliability for MODIS band 6 over a 16-day retrieval period.
• Supporting climate simulation models with validated surface radiative property data at a global 1km scale.

Strengths

• Produced daily with a 16-day data composite, providing frequent temporal updates.
• Global coverage at 30 arc second (1,000 meter) resolution, suitable for climate-scale analysis.
• Version 6.1 incorporates specific calibration improvements, including RVS, optical crosstalk, and polarization corrections.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Each product file contains just one data layer, which may require handling multiple files for a complete analysis.
