Range—

ET / ETo is a field-to-reference comparison. It is not an irrigation recommendation or a crop coefficient calibration by itself.

ETc = forecast ETo × planning Kc. The recent-ratio option uses recent measured ET/ETo as a planning proxy; use a locally validated crop coefficient for irrigation decisions.

UNDERSTAND THE RECORD

Measurements with context.

Field ET represents observed crop and soil water loss. Reference ETo represents atmospheric demand over a reference surface. The dashboard keeps coverage, timing, and source status visible so a number is not separated from its measurement context.

Daily ET & coverage

Each valid 30-minute ET rate is integrated over its interval. Short internal gaps can be linearly reconstructed, and larger daily gaps can use a reference-ET-scaled estimate when enough recent measured data exist. Measured and estimated contributions remain distinguishable in the data record.

Reference ET

CIMIS ETo is paired to each field station according to the project configuration. Pairings should be reviewed by the network manager for agronomic representativeness.

Updates

Live SmartFlux collection is designed to run hourly. This page checks the published API periodically while open. The seven-day outlook is refreshed by the hourly collector when forecast service is available.
