MCD19A1N: Daily Land Surface Reflectance at 500m/1km

Global daily satellite data provides surface spectral reflectance corrected for atmospheric gases and aerosols. The dataset is produced by the Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm, which uses time series analysis and pixel- and image-based processing. It is based on Version 6.1 Level-1B products from the combined Terra and Aqua MODIS sensors.

Use Cases

• Monitoring land surface changes based on daily, atmospherically corrected reflectance data.
• Validating atmospheric correction algorithms using the MAIAC algorithm's pixel- and image-based processing.
• Analyzing surface radiative properties for climate models using the Bidirectional Reflectance Factor (BRF).
• Studying aerosol impacts on surface reflectance using the corrected spectral bands.

Strengths

• Provides daily, near real-time (NRT) global coverage.
• Features a sophisticated atmospheric correction algorithm (MAIAC) that uses time series analysis.
• Includes calibration improvements for Terra MODIS data from 2012-2017.

Limitations

• Specific column names and dataset size (rows, file size) are not provided in any source.
• License is ambiguously listed as 'other-license-specified' without further detail.
• The listed last update date of 2026-04-09 appears to be a future date, which may indicate a metadata error.
