MODIS White-Sky Albedo for Band 6 at 1km Global Resolution

White-sky albedo data for MODIS spectral band 6 is produced daily from Terra and Aqua satellite observations at 30 arc-second resolution. The LPCLOUD organization generates this global Climate Modeling Grid product using a 16-day temporal window weighted to the ninth day. This dataset supports climate simulation models.

Use Cases

• Model surface energy balance in climate simulations using the white-sky albedo layer for band 6.
• Assess temporal changes in surface reflectance by analyzing the daily albedo values aggregated over a 16-day window.
• Filter data quality for scientific applications by applying the band-specific quality flags described in the user guide.
• Compare albedo values across different spectral bands by referencing the suite of 10 white-sky and 10 black-sky albedo layers.

Strengths

• Daily temporal resolution provides frequent surface condition updates.
• Global spatial coverage at 30 arc-second resolution supports worldwide climate models.
• Product is part of a suite with 20 albedo layers for different spectral bands.

Limitations

• Each product file contains only one data layer, requiring multiple files for multi-band analysis.
• Data accuracy depends on the quality of the full inversion results, which must be isolated using quality flags.
• Known issues exist and require consultation of the MODIS/VIIRS Land Quality Assessment website.
