陆地上空大气温度廓线及地面辐射参数的卫星遥感
Remote Sensing of Temperature Profile and Surface Emissivity over Land

摘要: 本文利用TIROS—N系列卫星HIRS—2资料，结合相应的无线电探空，提出了一个处理卫星遥感方程中地面辐射因子的新方法，在反演大气温度廓线的同时，还获得了地面温度及其比辐射率与统计反演方法得到的结果对比表明，本文的方法对低层大气的温度反演精度有明显的提高。地面温度及其比辐射率的结果也是合理的。Abstract: A physical method, based on the simplification of surface radiation terms in remote sensing equations, has been suggested to retrieve surface temperature, vertical temperature profile and surface emissivity from the first eight channel observations of TIROS—N/HIRS-2. Analyses of several examples indicate that much more accurate air temperatures in lower atmospheres than a statistical technique can be obtained by this method. The results of surface temperature and surface emissivity are also reasonable
