MART算法在大气水汽层析中的应用研究

Application of MART Algorithm in Atmospheric Water Vapor Tomography

以香港连续运行参考站数据为解算实例,对MART算法进行修正,并将其应用于水汽层析方程的解算,并研究了垂直分辨率对层析结果的影响。将层析解算的结果与京士柏探空站资料反演的水汽密度进行对比分析。实验结果表明,采用修正的MART算法能够用于水汽层析的解算,层析结果与探空站资料反演的结果符合得较好,采用垂直分辨为425m更能反映出大气水汽实际分布特性。

The HongKong continuously operating reference station data is used for the calculating examples,and the MART algorithm is modified,and applied to the calculation of water vapor tomography equations.Then the influence of the vertical resolution on the tomographic result is studied.Tomographic results of the calculating with Kings Park sounding station data inversion of the water vapor density are analyzed.The experimental results show that the modified algorithm of MART can be used for the calculation of water vapor tomography, the tomographic result accords well with the sounding station data inversion result, and the vertical resolution of 425 m can reflect the actual distribution of the atmospheric water vapor.
