MODIS/Aqua Land Surface Temperature/Emissivity Monthly L3 Global 0.05Deg CMG V061

The Aqua MODIS MYD11C3 product provides monthly global Land Surface Temperature and Emissivity values on a 0.05-degree Climate Modeling Grid. This NASA dataset is generated by compositing daily observations and includes layers for daytime and nighttime LST, quality control, view angles, and emissivity from specific infrared bands. The data is updated to Version 6.1, which incorporates calibration improvements from the underlying Level-1B products.

Use Cases

• Modeling global climate patterns based on monthly land surface temperature composites.
• Analyzing land surface emissivity variations based on data from specific MODIS infrared bands.
• Assessing data quality for thermal remote sensing applications based on included quality control layers.
• Studying diurnal temperature cycles based on separate daytime and nighttime observation layers.

Strengths

• Provides global coverage on a consistent 0.05-degree (approximately 5.6 km) grid.
• Includes both daytime and nighttime observations along with multiple quality assessment layers.
• Version 6.1 incorporates specific calibration improvements, including RVS and polarization corrections.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Known issues exist, requiring users to consult the external MODIS/VIIRS Land Quality Assessment website.
