MCD43D30: Daily Global Shortwave Albedo Parameters at 1km Resolution

Global daily data for the geometric parameter of the Bidirectional Reflectance Distribution Function (BRDF) and Albedo model for the shortwave broadband, produced by NASA using Terra and Aqua MODIS instruments. The dataset is generated daily at a 30 arc second (approximately 1,000 meter) resolution, temporally weighted to the ninth day of a 16-day observation window. This Climate Modeling Grid (CMG) product is designed for use in climate simulation models.

Use Cases

• Modeling surface energy balance in climate simulations based on shortwave broadband albedo parameters.
• Analyzing daily changes in land surface reflectance properties based on the geometric BRDF parameter.
• Integrating high-resolution albedo data into Earth system models based on the 1km global grid.
• Assessing data quality for scientific applications based on the band-specific quality flags mentioned in the user guide.

Strengths

• Daily temporal resolution using 16 days of MODIS data from both Terra and Aqua satellites.
• Global spatial coverage at a 30 arc second (approximately 1,000 meter) Climate Modeling Grid (CMG) resolution.
• Version 6.1 incorporates specific calibration improvements, including RVS, optical crosstalk, and polarization corrections.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Each product file contains just one data layer, which may complicate multi-parameter analysis.
