MCD43D52: Daily Global White-Sky Albedo for MODIS Band 1 at 1km Resolution

Global daily white-sky albedo data for MODIS band 1, produced by NASA using 16 days of Terra and Aqua satellite observations. The Climate Modeling Grid product has a 30 arc second (approximately 1,000 meter) resolution and is temporally weighted to the ninth day of the 16-day period. This Version 6 product was decommissioned on July 31, 2023, with users directed to the updated Version 6.1.

Use Cases

• Parameterizing land surface reflectance in climate models based on the white-sky albedo data.
• Analyzing daily surface radiative properties for MODIS band 1 as described in the product suite.
• Isolating high-quality full inversion results for science applications using the band-specific quality flags mentioned in the user guide.

Strengths

• Produced daily using 16 days of combined Terra and Aqua MODIS data.
• Covers the entire globe at a 30 arc second (1,000 meter) Climate Modeling Grid resolution.
• Improvements from previous version include better quality at high latitudes and weighting to the ninth day.

Limitations

• The Version 6 product has known issues, particularly over arid bright surfaces, and was decommissioned; users are urged to use Version 6.1.
• Column-level documentation is absent; field semantics must be inferred after download.
• Each product file contains just one data layer due to large file size.
