| Abstract | Surface Energy Balance Algorithm for Land (SEBAL) has been widely using by hydrologists, scientists to estimate the interaction and transformation among soil, plants and atmosphere. Recently, remote sensing has been used for SEBAL by the linkage to meteorological data. Bastiaanssen,AV.G.M (1997) has developed a SEBAL model based on the remotely sensed data which have visible, near infrared and thermal bands in the combination with a limited meteorological data to estimate the exchange energy of soil, plants and near surface atmosphere. From macro scale to micro scale, the SEBAL model can be applied for different level, from regional level to basin or field. This research attempted using SEBAL model to estimate Surface Energy Balance Components: evapotranspiration, soil heat flux, net radiation and sensible heat flux which vary on the continuous land surface. The most interesting part is to estimate sensible heat flux using the iteration processing in which the Monin-Obukhov length was used to define the stability conditions of the atmosphere. Finally, the research found out the simple way to estimate actual evapotranspiration for Jasmine Rice's fields in Roi Et and improved the limitation of the number of meteorological observation stations for Roi Et province, and showed up the applicability of this model for large area of Thailand |
