Computes the time average values for second order products V.T, V.S, U.T and U.S used in heat and salt transport computation. This is the wrapping around a modified version of the native cdfvT operator (adapted to set 4 files with only one variable in input) assuming its usage is:
cdfvT T-file S-file U-file V-file [-o output_file ] [-nc4 ]
... 'list_of_tags'
There are not CliMAF optional arguments.

Provider / contact : climaf at meteo dot fr for the wrapping
Inputs (in the order of CliMAF call): 4 datasets
- a dataset with temperature [T-file]
- a dataset with salinity [S-file]
- a dataset with zonal velocity component [U-file]
- a dataset with meridional velocity component [V-file]
Mandatory arguments: None
Optional arguments: None
Required files: None
Outputs:
- main output : a netcdf file (variables : vozout, vozous, vomevt and vomevs)
Climaf call example:: For more examples which are systematically tested, see cdftools.py and cdftransport.py
>>> cdef("period","198807")
>>> dt=ds(simulation="PRE6CPLCr2alb", variable="thetao", realm="O") # dataset with temperature
>>> ds=ds(simulation="PRE6CPLCr2alb", variable="so", realm="O") # dataset with salinity
>>> du=ds(simulation="PRE6CPLCr2alb", variable="uo", realm="O") # dataset with zonal velocity component
>>> dv=ds(simulation="PRE6CPLCr2alb", variable="vo", realm="O") # dataset with meridional velocity component
>>> my_cdfvT=ccdfvT(dt,ds,du,dv)
>>> cfile(my_cdfvT) # to compute the time average values for V.T, V.S, U.T and U.S
Implementation: The operator is implemented as a binary using cdftools cdfvT operator.
