Simulation of agricultural meteorological factors affecting evapotranspiration by fuzzy inference

In agricultural meteorological studies, the major difficulty is the determi nation of evapotranspiration (latent heat flux). There are numerous methods for estimating its value. However, these approaches yield accurate and suc cessful results proportionally with the complexity. The main purpose of thi s paper is to determine the effects of atmospheric, soil, and field measure d plant quantities on the latent heat flux by using the fuzzy inference sys tems techniques. The necessary measurements are recorded during two differe nt periods in the faba bean plant growth at an agricultural meteorology sta tion by considering a Bowen Ratio Energy Balance System.
