units of omega
units of omega
an ncdump of a netcdf history file shows the units of omega to be cubic meters per second, however in wrt_his.F the routine scale_omega is called before omega is written. This routine multiplies omega by pn and pm, so the units of omega on output are actually m/s.
Re: units of omega
Hi Wendy,
My understanding is that Omega as it appears in netCDF files is already dimensioned in m/sec, even though the attribute "units" tells that it is in m^3/sec (that is erroneous now, but true for very old versions of the code). As you have already seen, before writing Omega into netCDF file, it is multiplied by pm*pn and therefore has units of m/sec. I hope this helps. Good luck.
