我国中纬地区电离层总电子含量的一个经验模式

AN EMPIRICAL MODEL OF TOTAL ELECTRON CONTENT OVER THE CONTINENT OF CHINA

由新乡（３５．３°Ｎ，１１３．９°Ｅ）１９８１～１９８５年观测日本同步卫星ＥＴＳ－Ⅱ的总电子含量（ＴＥＣ）资料，利用付里叶分析方法得出了表示我国中纬地区上空电离层总电子含量的经验模式．ＴＥＣ模拟与观测资料的比较表明其误差范围在５％～２０％之间变化．

An adequate empirical model of TEC is supplied by Fourier hamonic analysis over Xinxiang (35. 3°N, 113. 9°E), middle latitude of China using observation of the radio beacon satellite ETS-Ⅱ during the descending half of the solar cycle from 1981 to 1985. The results of comparison of measured TEC values with those estimated from the empirical modelshow that their errors vary from 5% to 20% approximately.
