23	! i i i i i
24	!*****************************************************************************
25	! *
26	! This subroutine transforms temperature, dew point temperature and *
27	! wind components from eta to meter coordinates. *
28	! The vertical wind component is transformed from Pa/s to m/s using *
29	! the conversion factor pinmconv. *
30	! In addition, this routine calculates vertical density gradients *
31	! needed for the parameterization of the turbulent velocities. *
