MCD43D46: MODIS Black Sky Albedo for Band 5, Daily Global 1km Resolution

MODIS/Terra+Aqua BRDF/Albedo Black Sky Albedo Band5 Daily L3 Global 30ArcSec CMG V006 is a decommissioned satellite-derived data product. It provides daily black-sky albedo (directional hemispherical reflectance) for MODIS spectral band 5 at a 30 arc second (approximately 1,000 meter) resolution, produced by NASA using 16-day observation windows weighted to the ninth day. The product is formatted as a Climate Modeling Grid (CMG) covering the entire globe.

Use Cases

• Modeling surface energy balance in climate simulations based on the black-sky albedo parameter.
• Analyzing land surface changes over time based on daily global coverage at 1km resolution.
• Incorporating satellite-derived reflectance into land cover studies based on MODIS band 5 data.
• Assessing data quality for scientific applications based on the band-specific quality flags mentioned in the user guide.

Strengths

• Global spatial coverage designed for climate modeling grids.
• Daily temporal production using a 16-day observation window for stability.
• Specific focus on black-sky albedo for MODIS band 5 as part of a 20-layer product suite.

Limitations

• This Version 6 product was decommissioned on July 31, 2023, with users directed to use Version 6.1.
• Known issues in Collection 6, particularly over arid bright surfaces, suggest users should avoid substantive use.
• Description metadata is limited; actual data quality requires manual inspection after download.
