地基GNSS水汽反演实验与实践教学探讨

Discussion on experimental and practical teaching for water vapor inversion of ground-based GNSS

运用GNSS技术反演大气中的水汽含量是一种极有潜力、实用价值很高的大气水汽探测技术,由于其具有高精度、全天候、高时空分辨率、近实时等诸多优点,在气象业务中得到广泛应用。地基GNSS水汽反演作为南京信息工程大学测绘工程专业开设的特色专业课程之一,其实验与实习部分是加强学生实践能力和创新能力培养的重要环节,因此,从实践教学内容、教学方法、实验与实践平台、师资队伍建设等几方面对该课程的实践教学进行了探讨,以期为同类高校培养测绘气象交叉复合型人才提供参考。

The use of GNSS technology to invert water vapor content in the atmosphere is an extremely promising and practically valuable atmospheric water vapor detection technology,due to its high precision,ability for all-weather operation,high spatial and temporal,near real-time speeds and many other advantages,it has been widely used in the meteorological operations.Ground-based GNSS water vapor inversion is one of specialty course offered by Surveying and Mapping Engineering from Nanjing University of Information Science&Technology,its experimental practice is an important part of strengthening students practical ability and innovative ability training,therefore,this article discusses the practical teaching of the course from the aspects of practical teaching content,teaching methods,experimental and practical conditions,and construction of teaching staff,so as to provide reference for similar universities to cultivate surveying and mapping meteorological cross compound talents.
