MODIS/Aqua MYD11C1 V006: Daily Global Land Surface Temperature

MODIS/Aqua Land Surface Temperature/Emissivity Daily L3 Global 0.05Deg CMG V006 provides daily global land surface temperature and emissivity values on a 0.05-degree Climate Modeling Grid. The dataset includes daytime and nighttime observations of LST, quality control assessments, observation times, view zenith angles, clear-sky observation counts, and emissivity values for specific MODIS bands. It was decommissioned on July 31, 2023, with users directed to the updated Version 6.1 product.

Use Cases

• Monitoring urban heat island effects based on daily land surface temperature layers.
• Validating climate models using the global, gridded temperature and emissivity data.
• Analyzing diurnal temperature cycles using separate daytime and nighttime observations.
• Assessing surface energy balance and emissivity for specific land cover types.

Strengths

• Provides global coverage with a consistent 0.05-degree (approximately 5.6 km) grid.
• Includes multiple data layers such as quality control, observation times, and view angles for each temperature measurement.
• Version 6 improvements include removal of cloud-contaminated LSTs and updates to the split-window algorithm coefficient table.

Limitations

• Dataset is deprecated (decommissioned July 31, 2023), directing users to a newer version.
• Column names and specific data structure are not provided in the available metadata.
• Conflicting 'last updated' dates exist between sources (2026-04-10 and 2023-02-25).
