Global Daily Black-Sky Albedo for MODIS Band 3

Global daily black-sky albedo data for MODIS band 3 is produced at 30 arc second (1,000 meter) resolution. The dataset is generated daily using 16 days of Terra and Aqua MODIS observations, temporally weighted to the ninth day. It is created by LPCLOUD for use in climate simulation models.

Use Cases

• Model surface energy balance by incorporating black-sky albedo for MODIS band 3 into climate simulations.
• Analyze temporal trends in surface reflectance using the daily, globally gridded albedo values.
• Assess land surface changes by comparing black-sky albedo across different geographic regions.
• Validate other albedo products using the band-specific quality flags described in the user guide.

Strengths

• Daily temporal resolution using a 16-day observation window.
• Global spatial coverage at 1,000 meter resolution.
• Includes band-specific quality flags for isolating high-quality results.

Limitations

• Each product file contains only one data layer, limiting simultaneous analysis of multiple bands.
• Known issues exist, requiring users to consult external assessment websites.
• The large file size may complicate data handling and processing.
