The characteristics of phased array weather radar and the structure of a NetCDF (Network Common Data Form) file, and the data and product generation of phasedarray weather radar by uploading the NetCDFstored data are discussed, with emphasis on the file structure and uploading procedures of NetCDF data. The uploading of NetCDF data and the product display are realized on the on the VC++ platform. The NetCDF data comes from an synchronous observation experiment in 2004, in which the USA’s new modified phasedarray weather radar of and Doppler radar are used. By means of the product, the comparison and analysis are conducted of the characteristics of two radar sets respectively through a specific application example.
