Daily Global Black Sky Albedo for MODIS Band 5

MODIS band 5 black-sky albedo data is produced daily from combined Terra and Aqua satellite observations at a 1-kilometer resolution. The LPCLOUD organization generates this Climate Modeling Grid product for global climate simulation models, using a 16-day rolling window temporally weighted to the ninth day.

Use Cases

• Modeling land surface energy budgets using the band 5 black-sky albedo layer.
• Assessing vegetation health and stress by analyzing temporal changes in near-infrared (NIR) reflectance represented by MODIS band 5 albedo.
• Validating climate model outputs against observed surface reflectance data from the 30 arc-second global grid.
• Filtering data for highest quality results using the band-specific quality flags described in the user guide.

Strengths

• Daily temporal resolution using a 16-day data window.
• Global coverage at a consistent 30 arc-second (1 km) spatial resolution.
• Product suite includes 10 distinct black-sky albedo layers for different spectral bands.

Limitations

• Each daily product file contains only one data layer, requiring multiple files for multi-band analysis.
• Known issues exist, requiring users to consult external assessment websites for full details.
• The large file size per layer may complicate data management and processing workflows.
