CASA: time averaged vs instantaneous pools and fluxes in output?

[SeanBryan51]

Whilst looking into the behaviour of the CABLE MPI driver during a CASA-CNP run, I noticed the MPI master driver is currently hard coded to output instantaneous pools and fluxes when writing the NetCDF CASA output:

CABLE/src/offline/cable_mpimaster.F90

Lines 840 to 841 in 7b87f9c

	CALL WRITE_CASA_OUTPUT_NC (veg, casamet, casapool, casabal, casaflux, &
	CASAONLY, ctime, &

But in the serial driver, it is hard coded to output time averaged pools and fluxes via sum_casapool and sum_casaflux:

CABLE/src/offline/cable_serial.F90

Lines 655 to 657 in 7b87f9c

	CALL WRITE_CASA_OUTPUT_NC (veg, casamet, sum_casapool, casabal, sum_casaflux, &
	CASAONLY, ctime, ( ktau.EQ.kend .AND. YYYY .EQ. &
	cable_user%YearEnd.AND. RRRR .EQ.NRRRR ) )

Is there any preference for one over the other? Perhaps this behaviour should be configurable at runtime via a namelist option.
