MCD43D64: Daily Global Nadir-Adjusted Reflectance for MODIS Band 3 at 1km Resolution

Daily global data produced using 16 days of Terra and Aqua MODIS observations, temporally weighted to the ninth day. The MCD43D64 Version 6.1 product provides Nadir BRDF-Adjusted Reflectance for MODIS band 3 at 30 arc second (1,000 meter) resolution, covering the entire globe for climate simulation models. It is produced by the National Aeronautics and Space Administration (NASA) and was last updated in March 2026.

Use Cases

• Modeling surface albedo for climate simulations based on the daily, globally-covered Climate Modeling Grid product.
• Analyzing land surface reflectance changes over time based on the daily, nadir-adjusted reflectance data.
• Isolating high-quality reflectance values for specific science applications based on the band-specific quality flags described in the user guide.

Strengths

• Daily temporal resolution produced using a 16-day observation window.
• Global spatial coverage at a consistent 30 arc second (approximately 1km) resolution.
• Version 6.1 incorporates specific calibration improvements including RVS, optical crosstalk, and polarization corrections.

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.
