MODIS Daily Global BRDF Albedo Quality Assessment Layer

MCD43D35 Version 6.1 provides a daily quality layer for MODIS band 3 reflectance data, derived from 16 days of Terra and Aqua satellite observations. This global Climate Modeling Grid product has a resolution of 30 arc seconds (approximately 1 kilometer). The dataset is produced by LPCLOUD using NASA MODIS instruments.

Use Cases

• Filtering high-quality full inversion results for albedo modeling using the band-specific quality flags.
• Assessing temporal consistency of land surface observations by analyzing the valid observation layer representing each of the 16 days in the retrieval period.
• Integrating quality-controlled MODIS band 3 data into climate simulation models via the global Climate Modeling Grid (CMG) product.

Strengths

• Daily global coverage at 30 arc second resolution.
• Derived from 16 days of combined Terra and Aqua MODIS data for temporal stability.
• Provides a specific quality layer for MODIS band 3, enabling targeted data validation.

Limitations

• Each product file contains only one data layer, requiring multiple downloads for full analysis.
• Known issues exist and require consultation of external MODIS/VIIRS Land Quality Assessment resources.
• Data are temporally weighted to the ninth day of a 16-day period, which may not represent instantaneous conditions.
