EFDC+ can currently write the native output in NetCDF-CF format for Windows and Linux. EFDC_Explorer (the pre-and post-processor for EFDC+) can also convert the binary files output by EFDC+ (*.OUT) to netCDF.nc files, including the derived water quality parameters. EFDC+ currently exports 44 parameters to NetCDF format. This allows EFDC+ output to be read and displayed on web servers.
