MODIS Terra Daily Surface Reflectance Climate Modeling Grid

LPCLOUD's MOD09CMG Version 6.1 product provides daily estimates of surface spectral reflectance for Terra MODIS Bands 1 through 7. Data is corrected for atmospheric conditions and resampled to a 5600-meter pixel resolution on a Climate Modeling Grid. The product includes 25 layers comprising spectral bands, brightness temperature, and quality assurance information.

Use Cases

• Modeling land surface albedo and energy balance using spectral reflectance from MODIS Bands 1-7.
• Assessing atmospheric correction accuracy by comparing QA bands with raw reflectance values.
• Analyzing surface temperature trends by incorporating Brightness Temperature data from thermal bands 20, 21, 31, and 32.
• Monitoring continental-scale vegetation changes over time using the corrected reflectance values on the 5600-meter CMG.

Strengths

• Includes 25 data layers for comprehensive analysis.
• Provides atmospheric correction for gasses, aerosols, and Rayleigh scattering.
• Data is resampled to a consistent 5600-meter resolution for climate modeling.

Limitations

• Known issues exist, requiring users to consult external quality assessment resources.
• Specific temporal coverage, update frequency, and data volume details are unavailable.
