Terra MODIS Daily Land Surface Temperature and Emissivity at 1km Resolution

NASA's MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 1km SIN Grid V061 dataset provides daily per-pixel land surface temperature and emissivity values at a 1-kilometer spatial resolution. The data is derived from the MOD11_L2 swath product and includes quality control assessments, observation times, and view angles. This version incorporates calibration improvements for the Terra MODIS instrument.

Use Cases

• Analyzing urban heat island effects using daytime and nighttime land surface temperature bands.
• Modeling surface energy fluxes by combining temperature data with emissivity values from bands 31 and 32.
• Assessing land cover changes over time using the daily temporal resolution and quality control flags.
• Validating climate models with global, 1km-resolution temperature observations.
• Studying diurnal temperature cycles using separate daytime and nighttime surface temperature measurements.

Strengths

• Provides daily global coverage at a consistent 1-kilometer spatial resolution.
• Includes associated quality control assessments, observation times, and view zenith angles for data validation.
• Version 6.1 incorporates specific calibration corrections for Terra MODIS infrared bands and look-up tables for 2012-2017.

Limitations

• Exact row count, file size, and total temporal coverage are not specified across the provided sources.
• Above 30 degrees latitude, pixel values represent an average of multiple clear-sky observations, which may reduce local precision.
• License information is inconsistently reported as 'other-license-specified' or null.
