基于Landsat8辐射模块耦合SEBAL模型蒸散发估算
|
摘要
蒸散发(ET)是干旱和半干旱地区生态水文循环过程的重要因素。Landsat8数据的波谱信息丰富、空间分辨率高,是通过遥感技术反演蒸散发的理想数据源。SEBAL模型是以陆面能量平衡为基础,物理意义明确;但净辐射估算影响其估算精度。研究详细阐述了基于Landsat8数据的辐射模块耦合SEBAL模型,旨在提高反演结果精度,满足在水文、生态和农业研究应用中的需要。
The evapotranspiration( ET) is important factor of the eco-hydrological process in arid and semi-arid region. The Landsat8 product which has abundant spectral information and high spatial resolution is an ideal data for inverting ET through remote sensing technology. The Surface Energy Balance Algorithms for Land( SEBAL) model based on land surface energy balance has clear physical meaning,but the accuracy of estimated ET using SEBAL model is sensitive to the accurate estimates of net radiation. To this end,a new radiation module to utilize landsat8 product has been coupled with SEBAL to better estimate ET. This study can improve the accuracy of the inverting ET and meet the needs in hydrology,ecology and agriculture studies.
