MCD43D19: Daily Global Land Surface Albedo Parameter at 1km Resolution

MCD43D19 Version 6 is a daily, global land surface dataset produced by NASA using 16 days of Terra and Aqua MODIS observations. It provides the isotropic model parameter for MODIS band 7 at a 30 arc-second (approximately 1-kilometer) resolution, temporally weighted to the ninth day of the 16-day period. This Climate Modeling Grid product was decommissioned on July 31, 2023, with users directed to the updated Version 6.1.

Use Cases

• Modeling land surface albedo for climate simulations based on the daily, global Climate Modeling Grid (CMG) format.
• Analyzing bidirectional reflectance distribution function (BRDF) parameters for MODIS band 7 in conjunction with volumetric and geometric parameters.
• Assessing surface radiative properties over arid, bright surfaces, with consideration for known aerosol representation issues in the input data.
• Isolating high-quality, full inversion results for science applications using the band-specific quality flags described in the user guide.

Strengths

• Global coverage at a consistent 30 arc-second (approx. 1km) spatial resolution.
• Daily production using a 16-day observation window from two satellite platforms (Terra and Aqua MODIS).
• Temporal weighting to the ninth day aims to provide a representative snapshot for the period.

Limitations

• The dataset (Version 6) was decommissioned on July 31, 2023, due to known issues in input surface reflectance products, particularly over arid bright surfaces.
• Description metadata is limited; actual data quality requires manual inspection after download, including the use of extensive QA data from other products.
• Each product file contains just one data layer, requiring multiple files for a complete parameter set.
