C.W. Thornthwaite mapped the global (*) potential of it, while the FAO recommends using an equation named after Penman and Montieth to estimate the reference variety of it.   Most accurately measured using a lysimeter, it can be calculated by dividing latent energy by the heat of vaporization.  For 10 points, name this phenomenon which estimates water removed from both bare surface and plants by vaporization.
