ECOSTRESS: Daily Global Evapotranspiration Data at 70m Resolution

ECOSTRESS Evapotranspiration PT-JPL Daily L3 Global 70m V001 is a NASA dataset providing daily evapotranspiration (ET) estimates derived from the ECOSTRESS instrument on the International Space Station. The data is generated using the PT-JPL algorithm and includes variables such as instantaneous ET, daily ET, canopy transpiration, and soil evaporation. The dataset has a spatial resolution of 70 meters and covers latitudes between 52 degrees north and 52 degrees south.

Use Cases

• Modeling plant water stress and drought conditions based on daily evapotranspiration estimates.
• Analyzing water use efficiency in natural ecosystems based on the canopy transpiration and soil evaporation variables.
• Studying the global water cycle and vegetation response to climate based on spatially continuous data between 52°N and 52°S.
• Creating derived products like the Evaporative Stress Index (ESI) based on the Level 3 ET data.

Strengths

• Data is sourced from the ECOSTRESS instrument on the International Space Station, providing a unique spatial perspective.
• Provides multiple ET-related variables, including daily ET, canopy transpiration, and soil evaporation.
• Covers a broad latitudinal range from 52 degrees north to 52 degrees south.
• Has a high spatial resolution of 70 meters for detailed analysis.

Limitations

• The description notes known data acquisition gaps and instrument anomalies between 2018 and 2023, which may affect temporal continuity.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
