public class EtoPenmanMonteithFao
extends org.gcube.dataanalysis.ecoengine.interfaces.StandardLocalInfraAlgorithm

This is an algorithm that returns the the calculation of The Penman-Monteith Evapotranspiration Estimation by FAO-56 Method. The input is a general tabular resource with eight columns (date, latitude, altitude, temperature, max temperature, min temperature relative humidity, wind speed, and radiation).
