How It Works

Calculate reference evapotranspiration (ET₀) using the FAO-56 Penman-Monteith equation, the gold standard for irrigation scheduling and crop water requirement estimation

Each component has a specific meaning:

  • FAO-56 Penman-Monteith equation — The fao-56 penman-monteith equation recorded for the patient or scenario being assessed.
  • Gold standard — The gold standard recorded for the patient or scenario being assessed.

Note: Interpret the penman-monteith et result against the clinical thresholds and context described above.

How to Use

Enter the FAO-56 Penman-Monteith equation, gold standard for the patient or scenario you are assessing. Calculate reference evapotranspiration (ET₀) using the FAO-56 Penman-Monteith equation, the gold standard for irrigation scheduling and crop water requirement estimation. Use the penman-monteith et result to inform your clinical assessment.
