ECOSTRESS Land Surface Temperature and Emissivity at 70m Resolution

ECOSTRESS Land Surface Temperature and Emissivity data provides atmospherically corrected temperature and emissivity values for plants and land surfaces. The dataset is derived from five thermal infrared bands using a physics-based Temperature and Emissivity Separation algorithm, offering a spatial resolution of 70 meters. Collected by the ECOSTRESS instrument on the International Space Station, this Version 1 product has been decommissioned as of May 21, 2025, with users directed to newer versions.

Use Cases

• Analyzing plant water stress and evapotranspiration using land surface temperature (LST) and precipitable water vapor (PWV) columns.
• Studying surface thermal properties and energy balance with emissivity values for five thermal infrared bands.
• Mapping urban heat islands or agricultural drought at a 70-meter resolution using georeferenced swath data.
• Assessing data quality and uncertainty for temperature and emissivity studies using the provided LST error and emissivity error columns.

Strengths

• Data is derived using a physics-based Temperature and Emissivity Separation (TES) algorithm, providing a validated retrieval method.
• Offers high spatial resolution of 70 meters for detailed analysis of land surface features.
• Provides global coverage between 52 degrees north and south latitude, capturing data across diverse ecosystems.
• Includes error estimates for both land surface temperature and emissivity, supporting uncertainty analysis.

Limitations

• The Version 1 product is decommissioned as of May 2025, indicating it is not the current operational dataset.
• Data acquisition experienced gaps due to instrument anomalies in 2018 and 2019, potentially affecting temporal continuity.
• Requires a separate georeferencing product (ECO1BGEO) for spatial analysis, adding complexity to the workflow.
