基于R语言的NetCDF文件分析和可视化应用

气象领域目前有多种广泛应用的气象数据分析和可视化工具集,包括GrADS、NCL、CDO和IDL等。R语言是一种由统计学家开发的统计计算和绘图的语言和环境,具有大数据处理的能力。R语言数量众多的扩展包为R语言用于海量气象数据分析和可视化提供了强有力的支持。基于R语言对NCEP发布的数据集进行了统计分析和可视化,展示了R语言在气象数据处理和可视化方面的应用。结合R语言提供的贝叶斯统计扩展包和高性能并行计算扩展包探讨了R语言在气象数据处理和可视化应用方面的广泛前景。

Visualized Application and Analysis of NetCDF Files Based on R Language

There is a range of visual tools used in Meteorological applications, which include GrADS, NCL, CDO, IDL, etc. R language is developed by a statistician with the capability of handling large data sets. There are many packages and subroutines developed by third parties for meteorological applications.Some of them can provide powerful support for analyzing and visualizing large meteorological data sets.The NCEP data analysis tool based on R language, which can be used for statistical analysis and visualization based the meteorological data sets, shows the effort towards using R language into meteorological applications. It is possible to extend the functions of this package by applying some Bayesian analysis and parallel computing technique.
