基于二进制-XML混合文件格式的SMOS盐度数据的处理和延伸应用仍处于初级阶段,其前提是对SMOS数据的提取。本文详细介绍了SMOS的文件格式和利用Matlab对SMOS文件进行读写操作的方法,在此基础上给出了提取SMOS数据的流程图和实例,为SMOS数据产品的开发打下了基础。
SMOS salinity data based on file format of hybrid binary-XML has just been processed and applied in the primary stage and extracting SMOS data is its premise. This paper presents a process of read-write hybrid binary-XML file format in details and gives a flow chart and an example of extracting SMOS data, laying the foundation of developing SMOS salinity product.
