| 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. * |
|---|
| 32 | ! It is similar to verttransform, but makes the transformations for * |
|---|
| 33 | ! the nested grids. * |
