MODIS BRDF Geometric Parameter for Band 5 Daily Global Data

Geometric parameter data for MODIS band 5 is produced daily from Terra and Aqua satellite observations at 30 arc-second resolution. The dataset is generated by LPCLOUD using a 16-day temporal window weighted to the ninth day for global climate simulation models.

Use Cases

• Derive BRDF and albedo values for MODIS band 5 using the geometric parameter alongside isotropic and volumetric parameters.
• Apply band-specific quality flags to isolate high-quality full inversion results for surface reflectance studies.
• Input the 30 arc-second resolution geometric parameter data into global climate simulation grids.
• Analyze daily temporal trends in land surface reflectance characteristics using the geometrically modeled parameter.

Strengths

• Data is produced daily, providing frequent updates.
• Global coverage at 30 arc-second (approximately 1,000 meter) resolution.
• Parameters are derived from 16 days of MODIS data from both Terra and Aqua satellites.

Limitations

• Each product file contains only one data layer, limiting immediate multi-feature analysis.
• Known issues exist, requiring consultation of external assessment websites.
• Specific row counts, file sizes, and sample data details are unavailable.
