基矛MATLAB GUI的水汽自动处理系统的设计与实现

在利用GAMIT软件解算得出对流层总延迟ZTD的基础上．通过MATIABGUI各控件的布局设计及其回调函数的编写，利用MATLAB的图形用户开发环境（GUIDE）设计实现了水汽自动处理系统。本系统具有气象数据查询，日期与年积日转换，利用GPS气象数据及探空气象数据计算水汽总量及水汽变化分析等功能．可避免使用复杂的程序运算得出天顶静力学延迟ZHD，天顶湿延迟ZWD等气象要素。同时具有界面友好，操作简单，可移植性强等特点，为使用者提供了方便的，可视化的气象数据查询及水汽总量计算方法，具有良好的实际应用价值。

Design and implementation of the MATLAB GUI-based automatic water vapor processing system

On the base of calculating out zenith total delay ZTD in the use of GAMIT software,then on the basis of layout design of each MATLAB GUI control unit and the programming of their callback function,the author design and ultimately accomplish the water vapor automatic processing system by using MATLAB graphical user development environment(GUIDE).This system has the functions of meteorological data query,the date and year accumulate conversion,and the function of calculating the precipitable water vapor and analyzing the water vapor changes by using GPS meteorological data and sound data.It can avoid using complex programs to get the zenith hydrostatic delay ZHD;zenith wet delay ZWD and other meteorological elements.At the same time this system has the characteristics of friendly interface,the operation is simple,strong portability and others.The system provides the user with convenient,visual meteorological data query and precipitable water vapor calculation method,and has a good practical value.
