MCD43D07: Daily Global BRDF Isotropic Parameter for MODIS Band 3 at 1km Resolution

MCD43D07 Version 6.1 provides the isotropic parameter for deriving Bidirectional Reflectance Distribution Function and Albedo values for MODIS band 3. This daily, global Climate Modeling Grid product is produced by NASA using 16 days of combined Terra and Aqua MODIS data at a 30 arc second (approximately 1,000 meter) resolution. Data are temporally weighted to the ninth day of each 16-day acquisition period.

Use Cases

• Calibrating climate models based on daily, global surface reflectance parameters.
• Analyzing land surface radiative properties using the BRDF isotropic parameter for MODIS band 3.
• Isolating high-quality full inversion results for science applications using the band-specific quality flags.
• Studying temporal changes in surface albedo using the daily, temporally-weighted data product.

Strengths

• Produced daily using data from two satellite platforms (Terra and Aqua MODIS).
• Global coverage at a consistent 30 arc second (1,000 meter) Climate Modeling Grid resolution.
• Version 6.1 incorporates specific calibration improvements including polarization correction and RVS approach changes.

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.
• Data may reflect temporal weighting and sensor-specific biases inherent to the MODIS platform.
