Aqua MODIS Daily Global Land Surface Temperature at 0.05-Degree Resolution

MYD11C1 Version 6.1 from NASA's LPCLOUD provides daily global land surface temperature and emissivity values on a 0.05-degree Climate Modeling Grid. The dataset includes daytime and nighttime observations, quality control layers, and emissivity data from specific MODIS bands. A single global granule consists of 7,200 columns by 3,600 rows.

Use Cases

• Modeling diurnal temperature range by analyzing daytime and nighttime LST layers.
• Assessing data reliability for specific grid cells using the provided quality control assessment layers.
• Calculating emissivity for surface energy balance studies using bands 20, 22, 23, 29, 31, and 32.
• Analyzing global temperature trends by aggregating daily LST values over the 7,200x3,600 grid.
• Masking ocean pixels for land-only analysis using the percentage of land in the grid layer.

Strengths

• Global coverage with a consistent 0.05-degree (approx. 5.6 km) grid resolution.
• Includes both daytime and nighttime observations for diurnal cycle analysis.
• Provides multiple data layers including LST, quality control, observation times, and view zenith angles.
• Derived from the higher-level MYD11B1 product, implying a standardized processing chain.

Limitations

• Known data quality issues exist, requiring users to consult the MODIS/VIIRS Land Quality Assessment website.
• Emissivity bands 31 and 32 are available for daytime observations only.
• The daily temporal resolution may be insufficient for sub-daily process studies.
