Update the desctruction rate of buoyancy variance


INTERFACE:

   subroutine do_epsb(nlev,dt,u_taus,u_taub,z0s,z0b,h,NN,SS)
DESCRIPTION:

Based on the value of epsb_method, this routine calls the appropriate routines for calculating the molecular destruction rate of $ k_b$, defined in (160). Presently, only a simple algebraic expression, described in section 4.20, is available in GOTM.


USES:

   IMPLICIT NONE
INPUT PARAMETERS:
   integer,  intent(in)                :: nlev
   REALTYPE, intent(in)                :: dt,u_taus,u_taub,z0s,z0b
   REALTYPE, intent(in)                :: h(0:nlev)
   REALTYPE, intent(in)                :: NN(0:nlev),SS(0:nlev)
