ECOSTRESS: Daily Global Evaporative Stress Index at 70m Resolution

ECOSTRESS Evaporative Stress Index PT-JPL Daily L4 Global 70m V001 provides daily global data on plant water stress and potential drought. The dataset is produced by NASA's ECOSTRESS instrument on the International Space Station, measuring between 52 degrees N and 52 degrees S. It contains variables for the Evaporative Stress Index (ESI) and Potential Evapotranspiration (PET), derived using the PT-JPL algorithm.

Use Cases

• Monitoring agricultural drought and irrigation needs based on the Evaporative Stress Index.
• Modeling ecosystem water use and carbon exchange based on evapotranspiration data.
• Assessing regional plant water stress for crop yield forecasting.
• Validating land surface and hydrological models using satellite-derived ET and PET.

Strengths

• Data is collected globally between 52 degrees N and 52 degrees S latitudes.
• Provides daily measurements at a 70-meter spatial resolution.
• Produced by NASA, an authoritative source for Earth observation data.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Data acquisition has known gaps and anomalies, including a period in 3-band mode from May 2019 to April 2023.
• Column-level documentation is absent; field semantics must be inferred after download.
