modtran4.3.1
大气校正软件MODTRAN4.3.1,MODTRAN里提供了6种差异显著且有代表性的大气模型,这些模型的温度、水汽、臭氧廓线都有明显差异。近北极冬季模型(Sub-Arctic Winter)具有最低陆表温度,中纬度冬季模型(Mid-Latitude Winter)次之;热带模型(Tropical)和中纬度夏季模型(Mid-Latitude Summer)具有最高的陆表温度。对流层顶,热带模型的温度反而是最低的,而近北极夏季模型(Sub-Arctic Summer)具有最高的温度。在这6种模型中,除陆表外的第二温度峰值高度出现在海拔50km左右,这里近北极夏季模型具有最高温度,中纬度夏季模型与之近乎相等,在这个海拔上近北极冬季模型的温度是最低的。1976美国标准模型(1976U.S. Standard)在这一系列模型中提供了一个近乎与中位数值的选择。(Atmosphere Correction Software Modtran 4.3.1, it provides six distinct and representative atmospheric models with distinct differences in temperature, water vapor, and ozone profiles.)
