Web15. dec 2006 · The simplified formula for the Penman equation proposed to estimate potential evaporation from open-water without recourse to wind data is E PEN ≈ 0.047 R S T + 9.5 - 2.4 ( R S / R A) 2 + 0.09 ( T + 20) ( 1 - RH / 100) where RA (MJ/m 2/d) is the extraterrestrial radiation. A simplified expression for the calculation of RA is also given.
The Penman equation describes evaporation (E) from an open water surface, and was developed by Howard Penman in 1948. Penman's equation requires daily mean temperature, wind speed, air pressure, and solar radiation to predict E.
