Daily Global BRDF Volumetric Parameter for MODIS Band 5

MCD43D14 provides the volumetric parameter for MODIS band 5, used alongside isotropic and geometric parameters to derive surface reflectance and albedo. This daily product is generated from 16 days of Terra and Aqua MODIS data at 1-kilometer resolution, temporally weighted to the ninth day. The dataset is produced by LPCLOUD for NASA's Earthdata platform.

Use Cases

• Derive albedo values for MODIS band 5 by combining the volumetric parameter with isotropic and geometric parameters.
• Assess surface reflectance dynamics for climate modeling using daily, 1-kilometer resolution volumetric parameter data.
• Filter for highest quality full inversion results in science applications using the band-specific quality flags.
• Study land surface properties over a 16-day rolling window, temporally weighted to the central day.

Strengths

• Daily temporal resolution enables tracking of rapid surface changes.
• Global spatial coverage at 1-kilometer resolution supports comprehensive climate models.
• Data integrates observations from both Terra and Aqua MODIS instruments.

Limitations

• Each product file contains only one data layer, requiring multiple files for full analysis.
• Data quality is dependent on the 16-day acquisition window and inversion success.
• Known issues exist, requiring users to consult external assessment websites.
