What's inside

  • Evapotranspiration
  • Drought Indices

What you can do with it

Typical work that data of this type supports.

  1. 01

    Irrigation scheduling

    Decide when and how much to irrigate.

    Because it has: Evapotranspiration

  2. 02

    Water accounting

    Track how much water crops actually consume across a command area.

  3. 03

    Drought indices

    Track SPI and SPEI style indices for declarations and relief.

    Because it has: Drought Indices

Where AI adds value

Ideas for machine learning and AI agents built on this kind of data.

  1. 01

    Field-scale ET

    Estimate crop water use per field by combining satellite and weather with ML.

  2. 02

    Demand forecasts

    Predict irrigation demand weeks ahead for canal and pump planning.

  3. 03

    Onset forecasts

    Predict drought onset months ahead from climate signals.
