MODIS Daily BRDF Isotropic Parameter for Band 7 at 1km Resolution

MCD43D19 Version 6.1 provides the isotropic model parameter for MODIS band 7, derived from 16 days of Terra and Aqua satellite data. This daily Climate Modeling Grid product offers global coverage at a 30 arc second (approximately 1 kilometer) resolution. The dataset is produced by LPCLOUD using MODIS instruments.

Use Cases

• Modeling land surface albedo for band 7 using the isotropic parameter alongside volumetric and geometric parameters.
• Incorporating daily, 1km-resolution BRDF parameters into climate simulation grids for temporal analysis.
• Filtering data quality for band 7 using the band-specific quality flags described in the user guide to isolate high-quality inversion results.

Strengths

• Daily temporal resolution with data weighted to a central ninth day.
• Global spatial coverage on a Climate Modeling Grid (CMG).
• 30 arc second (approximately 1km) spatial resolution.

Limitations

• Each product file contains only one data layer, requiring multiple files for a complete parameter set.
• Data derivation uses a 16-day rolling window, not instantaneous daily measurements.
• Users must apply quality flags to isolate usable data, indicating potential noise or incomplete inversions.
