ETm was measured by lysimeters. Temperature and relative humidity were registered whereas Rge and Rne were estimated. The Rne was the variable with laRgest effect on ETmf determination, followed by D and URm. The air temperature at 15:00 and the daily maximum temperature were variables of laRger association with ETmf among the variables with punctual time observations. Rge improved its relationship with ETmf when was analyzed with different tam ranges. The results confirmed Rne and D as the meteorological variables of highest relationship with evapotranspiration in plastic greenhouse grown crops in autumn. However, the degree of adjustment of this re...
