• Simulation study of evapotranspiration needs observatioin data of the corresponding land and environmental. Using models, hourly variation or even more rapidly evapotranspiration variation can be simulated. The simulation results should be verfied and compared with observation data, to modify and miprove the models reliability. The rapid variation of latent and sensible heat flux can be provided, most directly, using Eddy-correkation system. Beside this method of measurement, it is also important to measure standard atmosperic variables such as temperature, humidity, and wild velocity, and also solar radiation as the source of energy, These data can be used to evaluate the evapotranspiration using indirect methods of Penman-Monteith and Bowen ratio. The observation was conducted at Kyushu University Experimental Farm during summer and early of autumn year 2003. The land conditions chosen for thos research were grass field, bare field and paddy field. Observation results show the differences of environmentak variables and energy fluxes on each land condition.
