MODIS White Sky Albedo Daily Global Climate Grid

MCD43D58 Version 6.1 provides daily white-sky albedo measurements for MODIS band 7. LPCLOUD produces this dataset using 16 days of Terra and Aqua MODIS data at a 30 arc-second (1,000 meter) resolution. Data are temporally weighted to the ninth day of the 16-day acquisition period.

Use Cases

• Model surface energy budgets by integrating white-sky albedo for band 7 into climate simulation grids.
• Analyze temporal trends in surface reflectance using the daily, temporally-weighted albedo values.
• Assess albedo quality for specific applications by applying the band-specific quality flags described in the user guide.

Strengths

• Global coverage at 30 arc-second resolution suitable for climate models
• Daily production using a 16-day data window for temporal consistency

Limitations

• Each product file contains only one data layer, limiting simultaneous multi-band analysis
• Potential for known sensor issues as documented on the MODIS/VIIRS Land Quality Assessment website
