无线电掩星反演大气温度的电离层影响
The Influences of Ionosphere on the Radio Occultation Temperature Inversion
摘要
Abstract
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 .关键词
