MODIS Daily BRDF Isotropic Parameter for Band 4

MCD43D10 provides the isotropic parameter of the Bidirectional Reflectance Distribution Function for MODIS band 4, derived daily from Terra and Aqua satellite observations. This parameter, along with volumetric and geometric parameters, is used to calculate surface reflectance and albedo values at a 30 arc-second (approximately 1 km) global resolution. The dataset is produced by LPCLOUD using NASA MODIS data.

Use Cases

• Calculate daily albedo for MODIS band 4 by combining the isotropic parameter with volumetric and geometric parameters from companion files.
• Assess surface reflectance changes over time using the daily temporal resolution and the 16-day data aggregation window.
• Filter for high-quality data in climate models by applying the band-specific quality flags referenced in the user guide.
• Integrate BRDF parameters into land surface models for regions covered by the global Climate Modeling Grid (CMG).

Strengths

• Provides daily temporal resolution for surface reflectance parameters.
• Offers global spatial coverage on a Climate Modeling Grid (CMG).
• Data is produced using 16 days of MODIS observations from both Terra and Aqua satellites, improving retrieval stability.

Limitations

• Each product file contains only one data layer, requiring multiple files for complete analysis.
• Known issues exist, requiring users to consult external documentation for quality assessment.
• The 30 arc-second resolution (approx. 1 km) may be insufficient for fine-scale local studies.
