Global Daily Land Surface Temperature and Emissivity at 0.05-Degree Resolution

MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 0.05Deg CMG V061 provides daily land surface temperature and emissivity values on a global climate modeling grid. The dataset is derived from the MOD11B1 product by LPCLOUD and NASA. Each global granule consists of 7,200 columns and 3,600 rows.

Use Cases

• Modeling urban heat island effects by analyzing daytime and nighttime LST layers across global cities.
• Assessing surface energy flux using emissivity values from bands 20, 22, 23, 29, 31, and 32.
• Filtering for high-quality observations by applying the quality control assessment layer.
• Studying diurnal temperature cycles by comparing daytime and nighttime observation times and LSTs.
• Analyzing spatial patterns of clear-sky conditions using the number of clear-sky observations per grid cell.

Strengths

• Global coverage with 7,200 columns and 3,600 rows per granule.
• Provides separate daytime and nighttime observations for diurnal analysis.
• Includes multiple data layers: LST, quality control, observation times, view angles, and emissivities.

Limitations

• Known data issues exist, requiring users to consult the MODIS/VIIRS Land Quality Assessment website.
• Specific temporal coverage, update recency, and total row count are not provided in the input.
• Emissivity bands 31 and 32 are available for daytime observations only.
