Abstract

The summary of Grassi's thesis by Christiansen illustrates a multiple correlation approach to predicting evapotranspiration, Et. Grassi related evapotranspiration rates to all meterological and crop data provided by the authors in addition to theoretical solar radiation reaching the outer atmosphere. A sequential analysis techniqe was used in an attempt to obtain independent empirical coefficients for the meteorological variables and crop factors presented. In this procedure, Et was correlated with the first meteorological [va]riable, (either extraterrestrial and cloud cover, or incident solar radiation, [] evaporation in this case) using only those values of Et near the potential [] growth state. Then, the ratios of Et to the values obtained from the correlation equation were correlated with the next variable.
