EEMS allows the conversion of EFDC+ binary output to NetCDF-CF (NetCDF- Climate and Forecast) formatted data, which can be read and displayed on web servers.
The NetCDF files can be converted only when the model has outputs.
The user can select which parameters should be converted and the time period of the exported data as shown in Figure 1.
In the Time frame, Julian time for Start and End is from the model as default. However, the user can define a time range to export by entering a new time for the Start and End (note that the entered time must be between the start and end time of the model).
Time Steps: This is the time step for skipping the snapshot time of the model. The default value is 1, which means that the NetCDF file contains every model's snapshot.
Deflate Level: This is the compression factor for the NetCDF file, the value ranges from 0 to 9. The higher value of the deflate level, the smaller the file size but it will take more time to export to the NetCDF file.
In the File Creation frame, the user is given the option of EFDC+ generating a Single File, or Multiple Daily Files.The Multiple Daily Files option provides one netCDF file for each one day (24 hours) of model output.
NetCDF files (.nc files) are placed in the #analysis folder along with the EFDC output.
