MCD43D63: Daily Nadir-Adjusted Reflectance for MODIS Band 2 at 1km Global Scale

MCD43D63 Version 6.1 is a daily global dataset of nadir BRDF-adjusted reflectance for MODIS band 2. The National Aeronautics and Space Administration produces it using 16 days of Terra and Aqua MODIS data, weighted to the ninth day, at a 30 arc second (1,000 meter) resolution. This Climate Modeling Grid product is designed for use in climate simulation models.

Use Cases

• Modeling surface albedo for climate simulations based on the daily, globally-covered Climate Modeling Grid product.
• Analyzing land surface changes over time based on the daily nadir-adjusted reflectance data.
• Assessing the quality of remote sensing retrievals based on the band-specific quality flags mentioned in the user guide.
• Correcting for view-angle effects in satellite imagery based on the NBAR algorithm described.

Strengths

• Data is produced daily using a 16-day rolling window, providing frequent temporal coverage.
• Global coverage at a consistent 30 arc second (1,000 meter) spatial resolution.
• Version 6.1 incorporates specific calibration improvements, including polarization correction and RVS approach changes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Each product file contains just one data layer, which may complicate multi-band analysis.
• Row count is unknown, which may limit suitability assessment.
