MCD43D62: Daily Nadir-Adjusted Reflectance for MODIS Band 1, Global 1km

Global daily land surface reflectance data for MODIS spectral band 1, produced by NASA using 16 days of Terra and Aqua satellite observations. The dataset is processed to a 30 arc-second (approximately 1,000-meter) Climate Modeling Grid and temporally weighted to represent the ninth day of the 16-day acquisition period. It is part of the Version 6.1 BRDF/Albedo product suite, with improvements including polarization and calibration corrections.

Use Cases

• Modeling land surface energy balance based on nadir-adjusted reflectance.
• Analyzing temporal trends in surface reflectance for climate studies based on daily global coverage.
• Incorporating corrected satellite observations into climate simulation models as described for the Climate Modeling Grid.
• Isolating high-quality surface observations for specific science applications using the band-specific quality flags mentioned.

Strengths

• Data is produced daily using a 16-day rolling window from two satellite platforms (Terra and Aqua).
• Global coverage at a consistent 30 arc-second (approx. 1km) resolution for climate models.
• Version 6.1 includes 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.
