MCD43D37: MODIS Daily Global BRDF/Albedo Quality Data for Band 5

MCD43D37 Version 6 is a decommissioned NASA dataset providing daily quality assessment information for valid observations in MODIS band 5. It is produced from 16 days of combined Terra and Aqua satellite data at a 30 arc-second (approximately 1,000-meter) resolution, temporally weighted to the ninth day. The data is formatted as a Climate Modeling Grid (CMG) covering the entire globe.

Use Cases

• Filtering high-quality full inversion BRDF/Albedo retrievals based on the band-specific quality flags described in the user guide.
• Assessing observation reliability for MODIS band 5 over the 16-day retrieval period for climate simulation models.
• Investigating data quality impacts from known aerosol representation issues in Collection 6 over bright surfaces.

Strengths

• Global spatial coverage at a consistent 30 arc-second Climate Modeling Grid (CMG) resolution.
• Daily production using a 16-day observation window weighted to a central date for temporal stability.
• Specific focus on quality information for MODIS band 5, as part of a suite of MCD43D products.

Limitations

• This Version 6 product was officially decommissioned on July 31, 2023; users are directed to use Version 6.1.
• Known issues in Collection 6, particularly regarding aerosol impact on downstream products over arid bright surfaces, are noted.
• Column-level documentation is absent; field semantics must be inferred after download or from the user guide.
