MCD43D58: Daily Global White-Sky Albedo for MODIS Band 7 at 1km Resolution

Daily global white-sky albedo data for MODIS band 7, produced using 16 days of Terra and Aqua satellite observations. The dataset is produced by NASA and was decommissioned on July 31, 2023, with users encouraged to use the Version 6.1 product. Data are provided at a 30 arc second (approximately 1,000 meter) resolution on a Climate Modeling Grid.

Use Cases

• Parameterizing land surface reflectance in climate models based on the white-sky albedo data.
• Analyzing temporal changes in surface radiative properties based on daily, globally-complete coverage.
• Validating or improving albedo algorithms for satellite-derived products based on the MODIS band 7 spectral information.

Strengths

• Global spatial coverage on a Climate Modeling Grid (CMG) for use in simulations.
• Daily temporal production using a 16-day observation window weighted to the ninth day.
• Data is from the NASA MODIS instrument suite, a long-standing and well-documented satellite program.

Limitations

• This Version 6 product was decommissioned on July 31, 2023, due to known issues impacting data quality, particularly over arid bright surfaces.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
