ECOSTRESS: Global Land Surface Temperature and Emissivity at 70m Resolution

ECOSTRESS Gridded Land Surface Temperature and Emissivity (ECO_L2G_LSTE) Version 2 data provides atmospherically corrected temperature and emissivity values derived from five thermal infrared bands. The product is a gridded, 70-meter resolution dataset projected to a global 0.0006° grid, containing eight layers including land surface temperature, error, emissivity, and quality flags. It is collected by an instrument on the International Space Station to study plant water use and stress responses globally between 52° N and 52° S latitudes.

Use Cases

• Monitoring plant water stress and evapotranspiration based on land surface temperature measurements.
• Analyzing urban heat island effects using high-resolution (70m) thermal data.
• Assessing drought impacts on vegetation by tracking temperature anomalies over time.
• Validating and improving land surface models using the provided emissivity and quality flag layers.

Strengths

• Provides high-resolution (70-meter) global land surface temperature data.
• Contains eight scientifically derived layers, including error estimates and quality flags.
• Data is atmospherically corrected using a physics-based Temperature and Emissivity Separation (TES) algorithm.

Limitations

• Metadata on row count, file size, and specific column names is unavailable across all sources.
• Instrument experienced operational anomalies in 2018 and 2019, potentially creating data gaps.
• Spatial coverage is limited to latitudes between 52° N and 52° S.
