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.)
