摘要
利用半径法、完整傅里叶级数描述法和非线性回归法分别对安装在河北省境内国家天文台兴隆园区(40.2°N, 117.4°E)的Fabry-Perot干涉仪(FPI)获得的地基中高层大气气辉观测数据进行风速反演.反演结果表明,半径法、完整傅里叶级数描述法和非线性回归法均能很好地反演风速,在误差范围内反演结果存在很好的一致性.相对于半径法和完整傅里叶级数描述法,非线性回归方法更完整地利用了观测数据信息,反演结果可信度较高.
Three methods are used to derive neutral winds from mid-and upper atmospheric airglow measurements by a ground-based Fabry-Perot Interferometer(FPI),which was deployed at Xinglong station(40.2°N,117.4°E)in Hebei province.The three methods are the radius method,the complete Fourier series description method and the nonlinear regression fitting method,respectively.The retrieval results show that the three methods can derive the neutral winds correctly within a given range of error.The nonlinear regression fitting method is recommended among the three methods,because more comprehensive fringe information is taken into account to derive the neutral winds by this method.
