Aqua MODIS 8-Day Land Surface Temperature and Emissivity Grid

8-day composite data provides average per-pixel Land Surface Temperature and Emissivity (LST&E) with a 1 kilometer spatial resolution. The product is generated by NASA's Aqua MODIS instrument and processed by INPE, with the latest update in June 2025. It includes associated quality control assessments, observation times, view zenith angles, and clear-sky coverages.

Use Cases

• Analyze daytime and nighttime surface temperature bands to study diurnal temperature variations.
• Use the associated quality control assessments to filter data for reliable land surface temperature analysis.
• Apply the 1 km resolution grid and view zenith angles for spatial modeling of surface emissivity.
• Leverage the 8-day compositing period to track seasonal land surface temperature trends over time.

Strengths

• Provides data at a consistent 1 kilometer spatial resolution.
• Uses an 8-day compositing period aligned with the satellite's exact ground track repeat cycle.
• Includes multiple associated data layers like quality control and observation times.

Limitations

• Specific row count, column details, and sample size are unknown.
• The spatial coverage is defined as a 1,200 by 1,200 km grid, but the exact global coverage is unspecified.
• The temporal coverage and historical data range are not provided.
