One of the 44 executables compiled as part of the WRFDA system is the file da_rad_diags.exe. This program can be used to collect the 01_inv* or 01_oma* files and write them out in netCDF format (one instrument in one file with prefix diags followed by the instrument name, analysis date, and the suffix .nc) for easier data viewing, handling and plotting with netCDF utilities and NCL scripts. See WRFDA/var/da/da_monitor/README for information on how to use this program.
