Abstract

A value for the total amount of water that, theoretically, could be lost from soil and vegetation through evaporation and transpiration, if sufficient soil moisture were always available, may be obtained readily by multiplying a given time-period factor by the sum of time-unit means of positive centigrade temperatures divided by the number of time units in the period.
