ECOSTRESS: Daily Evaporative Stress Index for CONUS at 70 m Resolution

ECOSTRESS data from the International Space Station measures plant temperature to assess water needs and stress. The ECO4ESIALEXI Version 1 product provides a daily Evaporative Stress Index (ESI) for the Contiguous United States at a 70-meter pixel resolution, derived from clear-sky estimates of relative daily evapotranspiration. This NASA JPL dataset is used for applications like indicating agricultural drought and observing vegetation stress.

Use Cases

• Monitoring agricultural drought conditions based on the daily Evaporative Stress Index.
• Assessing vegetation stress for crop management based on relative evapotranspiration estimates.
• Analyzing regional water use and plant health over time based on daily ESI data.
• Validating hydrological and land surface models based on high-resolution evaporative stress metrics.

Strengths

• Provides data at a high 70-meter spatial resolution for the Contiguous United States.
• Includes variables for daily evaporative stress index, its uncertainty, and associated quality flags.
• Data is collected by the ECOSTRESS instrument on the International Space Station, offering a spaceborne perspective.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Data acquisition experienced gaps and anomalies in 2018, 2019, and 2020, as detailed in the known issues.
• Row count is unknown, which may limit suitability assessment.
