Tidal frequencies are always angular frequencies to simplify applying
sine and cosine. These have MKS units [rad s-1] but they are all
currently listed as [s-1].
Updated dOxygen comments for variables, e.g. [T-1 ~> s-1] becomes
[rad T-1 ~> rad s-1]. Updated get_param units. e.g. units="s-1"
becomes units="rad s-1".
No answers are changed, but the logged parameter units are different.
There are frequencies in MOM_internal_tides.F90 but these have not
been updated because they may be specified incorrectly. They are
used as if they are [T-1] but they are calculated as 2PI/period [rad T-1].
real, allocatable, dimension(:) :: frequency !< The frequency of each band [T-1 ~> s-1].
real :: period ! A tidal period read from namelist [T ~> s]
! The periods of the tidal constituents for internal tides raytracing
call read_param(param_file, "TIDAL_PERIODS", periods)
do fr=1,num_freq
period = US%s_to_T*extract_real(periods, " ,", fr, 0.)
CS%frequency(fr) = 8.0*atan(1.0)/period
enddo
All MOM6-examples cases have INTERNAL_TIDES=False and so can't
resolve this issue.
