dc.description.abstractEvapotranspiration (ET) constitute a large portion of hydrological cycle which is stabilizing energy balance at the surface as a consequence of change energy flux between land surface and atmosphere. Usually, rate of evaporation obtain from Meteorological services while data of evapotranspiration is rarely available. In this study, Surface Energy Balance Systems (SEBS) has been utilized to measure turbulent flux and evaporative fraction in order to estimate rate of evapotranspiration using remotely sensed data and meteorological observation. SEBS required three datasets. First data sets is meteorology observation consist of wind speed, air pressure, relative humidity and air temperature. Second dataset gained from satellite observation using MODIS/Aqua images to determine albedo, emissivity, leaf area index, NDVI and fractional vegetation coverage. Reliable equation need to support satellite observation image. The third data set is incoming and outgoing solar radiation which is important to determine value of net radiation. Once net radiation, soil heat flux, latent heat flux and sensible heat flux identified, ET evaluate using Penman-Monteith equation. Finally, result showed that, Penman-Monteith, Priestly Taylor and Pan evaporation method considered as the best algorithm to estimate ET in Penang Island but Makkink, Hargreaves and Thornthwaite are not suitable for the study area.en_US
