新玩法大学已经开发了几种混合中性大气延迟模型。在本文中，我们提出了UNB3m_pack，一个包，在FORTRAN和MatLab中的相应功能，提供中性大气信息估计使用UNB 3 m模式的子程序。UNB 3 m的主要目标是为全球导航卫星系统和其他跨大气层辐射测量技术的用户提供可靠的预测中性大气延迟。斜中性大气延迟是该软件包的主要输出，然而，它可以被用来估计天顶延迟，Niell映射函数值，延迟率，映射函数率，站压力，温度，相对湿度和大气柱中的水汽的平均温度。子程序使用一年中的日期、纬度、高度和仰角作为输入值。这个包的文件在开头有一个注释部分，解释子例程如何工作以及输入和输出参数是什么。子程序是独立的，即，他们不需要任何辅助文件。用户只需将一个或多个可用文件添加到他/她的软件中，并以适当的方式调用它们。
Several hybrid neutral atmosphere delay models have been developed at the University of New Brunswick. In this paper we are presenting UNB3m_pack, a package with subroutines in FORTRAN and corresponding functions in MatLab which provides neutral atmospheric information estimated using the UNB3m model. The main goal of UNB3m is to provide reliable predicted neutral atmosphere delays for users of global navigation satellite systems (GNSS) and other transatmospheric radiometric techniques. Slant neutral atmosphere delays are the main output of the package, however, it can be used to estimate zenith delays, Niell mapping functions values, delay rates, mapping function rates, station pressure, temperature, relative humidity and the mean temperature of water vapor in the atmospheric column. The subroutines work using day of year, latitude, height and elevation angle as input values. The files of the package have a commented section at the beginning, explaining how the subroutines work and what the input and output parameters are. The subroutines are self-contained, i.e., they do not need any auxiliary files. The user has simply to add to his/her software one or more of the available files and call them in the appropriate way.
