Estimation of Regional Evapotranspiration through Remote Sensing
Models used for the remote estimation of evapotranspiration are evaluated using aircraft observations over two distinct vegetation regimes in southwestern Australia. Single-source models using an empirically determined excess resistance term performed better than a two-source model, which does not require such a parameterization. The mean absolute difference between measured and estimated value...
متن کاملStudy on Calculation of Land Surface Evapotranspiration Using Remote Sensing
Evapotranspiration (ET) plays a significant role in regional and global climates through its partitioning in hydrological cycles, and its estimation is thus of a great importance in assessing ground water and surface water resources, predicting crop yield and planning land use. For experimenting the possibility to assess the hydrological responses of ecological restoration in the Western Chines...
متن کاملComparing Three Approaches of Evapotranspiration Estimation in Mixed Urban Vegetation: Field-Based, Remote Sensing-Based and Observational-Based Methods
Despite being the driest inhabited continent, Australia has one of the highest per capita water consumptions in the world. In addition, instead of having fit-for-purpose water supplies (using different qualities of water for different applications), highly treated drinking water is used for nearly all of Australia’s urban water supply needs, including landscape irrigation. The water requirement...
متن کاملA methodology for estimation of surface evapotranspiration over large areas using remote sensing observations
We propose a simple scheme to estimate surface evaporation over large heterogeneous areas using remote sensing observations. Our approach is based on a relationship between easily measured surface parameters (e.g. radiometric surface temperature) and a surrogate for effective surface resistance. Preliminary results, using remotely sensed data sets from AVHRR NOAA-14 over the Southern Great Plai...
متن کاملRegional evapotranspiration estimation based on a two-layer remote-sensing scheme in Shahe River basin
Land surface evapotranspiration (ET) derived from remote sensing data has significant meaning for plant growth monitoring, crop yield assessment, disaster monitoring and understanding energy and water cycle in river basin area and surrounding regions. In the study, we developed a land surface ET remote sensing retrieval system to estimate the daily ET in Shahe river basin using the TM\ETM+ imag...
