MCD43D62: Daily Nadir-Adjusted Surface Reflectance for Climate Models

MODIS/Terra+Aqua BRDF/Albedo Nadir BRDF-Adjusted Reflectance Band 1 data is a daily, global satellite product at 30 arc-second (1,000-meter) resolution. The dataset is produced by NASA using 16 days of MODIS observations, weighted to the ninth day, for use in climate simulation models. This specific version (V006) was decommissioned on July 31, 2023, with users directed to the updated V6.1 product.

Use Cases

• Modeling land surface albedo for climate simulations based on the daily, global Climate Modeling Grid (CMG) data.
• Analyzing surface reflectance trends over bright, arid regions using the nadir BRDF-adjusted reflectance (NBAR) algorithm.
• Assessing data quality for scientific applications using the band-specific quality flags described in the user guide.

Strengths

• Global spatial coverage at a consistent 30 arc-second (1,000-meter) resolution.
• Daily temporal production using a 16-day observation window from two satellite platforms (Terra and Aqua).
• Data is temporally weighted to a specific ninth day, providing a consistent reference point.

Limitations

• This specific version (V006) is decommissioned and contains known issues, particularly over arid bright surfaces, per the description.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes a large file size where each product contains just one data layer, which may affect storage and processing.
