NCEP FNL全球分析资料的解码及其图形显示
Decoding and Graphic Display of the NCEP FNL Global Analysis Data
【摘要】 美国环境预报中心(NCEP)的FNL资料分辨率较高且融合了大量的观测资料及卫星反演资料,被广泛用于数值模式及天气、气候的诊断分析研究中。本文对该类资料的解码程序及绘图时所需控制文件、索引文件生成方法进行介绍,通过一系列批处理命令,可以进行大量FNL资料的解码及绘图处理,为科研工作者在资料内容提取和图形显示等方面的工作提供一定的参考。
【Abstract】 The FNL data of NCEP assimilated a large amount of observational data and satellite inverse data,has been widely used in numerical models and weather and climate research in the diagnostic analysis and research.This article introduced the decoding procedure and information required for graphics processing control files,index files when it was drawing in PC-GrADS software.Using a series of batch commands,we can conduct a large number of FNL data decoding and graphics processing,it can give some reference for the research in content extract and graphic display.
