This tool can convert non-rotated coordinate to rotated coordinate and vice versa. The pivot of rotations is based on CORDEX domains. For extracting data from CORDEX netcdf files, you should convert your regular coordinate to rotated coordinate by this tool and then extract your data by using rotated coordinate and rlat/rlon variables in your file. You can extract data by any language programming or you can use Netcdf Extractor in this website.
For checking the correctness of the tool, you can use TLC(Top Left Corner) of each domain in CORDEX Domains and convert non-Rotated to rotated and vice versa.
If you want extract data from CORDEX NetCDF files you can do it simply by using CORDEX Data Extractor
