利用掩星的附加相位延迟数据，对标准的几何光学大气反演算法进行了研究。探究电离层的电子密度对温度反演的影响，按照标准的几何光学反演算法得到的干温度与无线电探空仪数据的平均相对误差小于5％。将经过两种方法电离层修正后反演得到的温度与CDAAC的数据进行了对比，实验证明电离层残差对温度反演的影响随着高度的增加而增大，在25 km以上是造成温度反演误差的主要因素，弯曲角电离层修正法要优于相位电离层修正法。%T his paper uses the excess phase delay data of occultation to make some re‐search on the standard geometric optic algorithm of atmospheric inversion .It explores the in‐fluences of electron density on the temperature inversion .The average relative error between dry temperature w hich used the standard geometric optic algorithm and radiosonde data is less than 5% .Comparing the inversion temperature after the calibration of two ionosphere calibration methods with the CDAAC’s data ,the result shows that the influence of the iono‐sphere on the temperature inversion increases with the increase of the height .Above 25km ,it is the main factor which causes the temperature inversion errors .The bending angle calibra‐tion method is better than the phase calibration method .
