SEBAL-based sensible and latent heat fluxes in the irrigated Gediz Basin, Turkey

Surface Energy Balance Algorithm for Land (SEBAL) is a relatively new param eterization of surface heat fluxes based on spectral satellite measurements . SEBAL requires spatially distributed, visible, near-infrared and thermal infrared data, which can be taken from Landsat Thematic Mapper. The SEBAL p arameterization is an iterative and feedback-based numerical procedure that deduces the radiation, heat and evaporation fluxes. The sensible and laten t heat fluxes across the lower Gediz River Basin in Western Turkey have bee n estimated. The energy balance during satellite overpass, and the integrat ed 24 h fluxes are computed on a pixel-by-pixel basis. The temporal variabi lity in heat fluxes between June and August will be evaluated. The effect o f irrigation on the partitioning of energy and crop water stress is discuss ed.
