Terra MODIS Daily Surface Reflectance on 5.6km Climate Grid

MODIS/Terra Surface Reflectance Daily L3 Global 0.05Deg CMG V006 provides atmospherically corrected surface reflectance estimates from the Terra satellite's MODIS sensor. The dataset contains 25 layers, including spectral reflectance for bands 1-7, brightness temperature from thermal bands, and quality assurance data, resampled to a 5600-meter Climate Modeling Grid. This version 6 product was decommissioned in July 2023, with users directed to the updated Version 6.1.

Use Cases

• Analyzing global land surface reflectance trends using the seven corrected spectral bands.
• Inputting gridded surface reflectance and brightness temperature data into climate simulation models.
• Assessing data quality for downstream products like vegetation indices using the Quality Assurance layers.
• Studying aerosol impacts on surface reflectance retrievals flagged in the quality data.

Strengths

• Provides 25 data layers, including surface reflectance for 7 spectral bands and 4 thermal brightness temperature bands.
• Data is corrected for atmospheric gases, aerosols, and Rayleigh scattering.
• Corrections were implemented to reduce striping artifacts in bands 5-7 for data acquired after November 1, 2000.

Limitations

• This Version 6 product has been decommissioned; an updated Version 6.1 is recommended.
• Known issues include potential incorrect 'High Aerosol' flagging over bright surfaces at high view angles.
• Sources conflict on the last updated date, reporting both 2023-02-17 and 2026-03-13.
