摘要: 本文利用我国西北地区有代表性的3个测站的常规探空资料,应用大气折射理论和统计学方法建立了大气折射指数垂直分布的三种统计模式。计算结果表明:目前使用的4/3地球半径模式精度较差,只能在离地面1 km高度以下使用,才能保证精度;改进等效地球半径模式的精度最高;指数模式在离地面3 km高度以下使用精度也可保证。
关键词: 大气折射指数统计模式等效地球半径参考大气射线轨迹    
Abstract: In this paper,conventional radiosonde data from three representative observational stations in northwest region of China are used to establish three statistical models for the vertical distribution of the atmospheric refractive index based on the atmospheric refractive theory and the statistical approach.Results show that the current 4/3 effective earth's radius model has the lowest accuracy and can be used only below the height of 1 kilometer over the surface to guarantee sounding accuracy while the modified effective earth's radius model has the greatest accuracy.It is found that accuracy can be guaranteed by using the exponential model when below 3 kilometers over the surface.
Key words: Atmospheric refractive index    Statistical model    Effective earth's radius    Reference atmosphere    Ray tracing
