MODIS Daily Global Albedo Quality Assessment for Band 6

MCD43D38 Version 6.1 provides daily quality assessment data for MODIS band 6 valid observations, derived from 16 days of Terra and Aqua satellite measurements. The LPCLOUD organization produces this global Climate Modeling Grid product at a 30 arc second resolution. Data are temporally weighted to the ninth day of the retrieval period.

Use Cases

• Filtering MCD43D albedo products using the band 6 valid observation quality layer to isolate high-quality inversion results.
• Assessing temporal consistency of MODIS band 6 observations across the 16-day retrieval period for climate trend analysis.
• Integrating the quality flags into land surface models to improve the reliability of albedo-driven energy balance calculations.

Strengths

• Daily global coverage at 30 arc second resolution suitable for climate-scale analysis.
• Quality layer represents observations from each of the 16 days in the retrieval period, providing temporal context.

Limitations

• Each product file contains only one data layer, limiting immediate multi-band analysis.
• Known issues exist, requiring users to consult external quality assessment resources.
• The large file size per layer may complicate handling for regional studies.
