When the time-averaging option was originally added to NCOM, only a subset of the history-file quantites were included. For completeness in NCOM 1.4, time-averaged counterparts to all of the instantaneous fields were added where necessary.
The following table lists all of the new time-averaged history-file quantities added to NCOM 1.4. The first column lists the name of the field on the netCDF file; the second lists the corresponding name in the NCOM code itself; the third is the name of the new time-averaged variable in the NCOM code. Note that the netCDF variable name is the same for either time-averaged or instantaneous fields; the netCDF attribute 'time_rep' indicates whether the quantity is time-averaged or not.
