Estimation of Evapotranspiration Using Remote Sensing Data and Grid Computing: A Case Study in Dobrogea, Romania
نویسندگان
چکیده
Estimating evapotranspiration is essential for understanding the water cycle of natural systems and for the management of the water resources in landscape systems. This paper presents a procedure to calculate the evapotranspiration using the remote sensing data and Grid Computing. Evapotranspiration was retrieved during satellite overpass and integrated for 24 hours on pixel-by-pixel base for daily estimation. As a result, a LST (Land Surface Temperature) and ET (Evapotranspiration) maps over the Dobrogea region were used for comparison with measured data provided by meteorological stations. The results are promising and appear to provide acceptable estimation over the study area. Key-Words: remote sensing, grid computing, evapotranspiration, land surface temperature
