EFDC+ allows the export of NetCDF-CF (NetCDF- Climate and Forecast) formatted data. This allows EFDC+ output to be read and displayed on web servers. 

...

• Establish an interface standard that simplifies the design of new software for accessing geoscience data.

The new version of EFDC+ is able to export the native output in NetCDF-CF format for Windows and Linux. EE_Explorer, the pre- and post-processor for EFDC+ can also convert EFDC  *.OUT files to netCDF .nc files, including the derived WQ parameters.  EFDC+ currently exports 44 parameters to NetCDF format..

EFDC+ exports the NetCDF files at the same interval that it produces the model linkages files, which is set in the tab for Timing and Linkage | Linkage | NetCDF. 

The main configuration for NetCDF output is in the EFDC_Exlporer Linkage | NetCDF tabs as shown in Figure 1 240419309.  Here the user can turn on netCDF output by checking the Output to NetCDF checkbox.  The user may select the level at which the NetCDF data is compressed with the Deflate Level setting. This can range from 1, no compression, to 9 for maximum compression, but is recommended by UNIDATA to be set to 2 for the best balance between file size and speed.

Info
titleNote
  • After running the model, the user needs to close the EFDC+ run window using the carriage return before viewing the netCDF output. Using the X button on the run window will mean NetCDf ouput will not be written. 
  • The calendar date is the default date in the NetCDF output.
  • Layer ordering in the water column will be reversed in NetCDF compared to that of EE.
