MCD43D35: Daily Global BRDF/Albedo Quality Data for Climate Models

MCD43D35 Version 6.1 provides daily quality assessment information for MODIS band 3 reflectance data at 30 arc-second (1,000-meter) resolution. The dataset is produced by NASA using 16 days of combined Terra and Aqua satellite observations, temporally weighted to the ninth day, and covers the entire globe. It is specifically designed for use in climate simulation models, with users urged to consult the detailed User Guide for applying quality flags.

Use Cases

• Filtering high-quality full inversion results for land surface studies based on the band-specific quality flags.
• Assessing observation reliability for MODIS band 3 within climate models using the daily valid observation quality layer.
• Improving land surface parameterization in climate simulations based on the 30 arc-second Climate Modeling Grid (CMG) product.

Strengths

• Produced daily with a 16-day observation window, providing frequent temporal coverage.
• Global spatial coverage at a consistent 30 arc-second (1,000-meter) resolution.
• 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.
• Each product file contains just one data layer, which may require handling multiple files for a complete analysis.
