摘　　要：NetCDF是广泛应用于海洋大气等领域的通用网络数据格式,具有良好的自描述性和平台无关性,已经成为事实上的海洋大气领域数据交换标准。在大量NetCDF通过网络进行发布的前提下,要实现有限的带宽限制下避免大型文件下载操作来实现对NetCDF文件的快速选取和数据预览,互联网的云服务技术为这种需求提供了解决方法。本文利用SOA框架结合NetCDF Java提供Web Service服务接口实现对NetCDF文件必要信息的快速抽取,部分的解决了网络带宽限制和大文件下载之间的矛盾,成果应用具有一定的普遍适用性。NetCDF is a general network data format widely used in the field of ocean and atmosphere,with good self-description and platform independence.NetCDF now has been the standard of data ex-change in the field of the oceanic atmosphere.Because a large number of NetCDF files have to be distributed through the network,to achieve fast file selection and preview of NetCDF files by avoiding large file download with limited bandwidth limitation,the Internet cloud service technology provides a solution to this problem.This paper makes use of SOA framework and NetCDF Java to provide Web Service interface to extract the necessary information of NetCDF files,and partly solves the contradiction between network bandwidth limitation and large file download.The application of the result has some universal applicability.
