OpenET Data Explorer
Satellite-based field-scale evapotranspiration (ET) data for agricultural water management and irrigation scheduling across the contiguous United States. Provides daily, monthly, and annual ET at 30m resolution from an ensemble of six Landsat-driven models, accessible via a Data Explorer, API, and the FARMS tool.

Terms explained
What you can do with it
Typical work that data of this type supports.
- 01
Irrigation scheduling
Decide when and how much to irrigate.
Because it has: Evapotranspiration
- 02
Water accounting
Track how much water crops actually consume across a command area.
- 03
No-gauge areas
Monitor places with no ground stations.
Because it has: Remote sensing
Where AI adds value
Ideas for machine learning and AI agents built on this kind of data.
- 01
Field-scale ET
Estimate crop water use per field by combining satellite and weather with ML.
- 02
Demand forecasts
Predict irrigation demand weeks ahead for canal and pump planning.
- 03
Segmentation
Map water, crops and land use pixel by pixel with deep learning.
