摘要
表面能量平衡系统是应用卫星对地观测的可见光、近红外和热红外波段资料,结合实测气象数据或大气模式输出数据,根据表面能量平衡原理估算不同尺度的地表大气湍流通量,从而估算地表相对蒸散的一种方法。在水文地质、NOAA卫星及地面气象数据的基础上,对大同、忻州和临汾3个盆地的区域蒸散进行了估算,评价了区域蒸散的分布规律,并对其影响因素进行了分析。
Using visible and infrared satellite remote sensing data, SEBS (Surface Energy Balance System) is based on land surface energy balance theory combined with the in-situ meteorological data or the product of atmospheric numerical model to estimate land surface turbulent flux and the relative evaporation at different scales. On the basis of hydro-geological data, NOAA satellite data and the meteorological data, SEBS was used in this paper for the estimation of actual evaportranspiration of three basins. The distribution of regional evaportranspiration was evaluated and the influence factors were also analyzed in this paper.
