Transect with topography

Dear NCL users,

I'm trying to plot a transect with the contour masked by topography, but I
can't realize how to do that. I have looked for an example showing how to do
it, but I couldn't find it.
I'm using example trans_1.ncl to make the transect.
My data is in pressure levels and I have topography in meters. They are
shown below, transQ it's the data interpolated in a great circle:

Variable: transQ
Type: float
Total Size: 502740 bytes
            125685 values
Number of Dimensions: 4
Dimensions and sizes: [caso | 7] x [tempo | 19] x [nivel | 21] x [pts |
45]
Coordinates:
            caso: [1..7]
            tempo: [ 0..2160]
            nivel: [1001..50]
            pts: [0..44]
Number Of Attributes: 3
  _FillValue : -999
  xcoord : <ARRAY of 45 elements>
  ycoord : <ARRAY of 45 elements>

Variable: terreno
Type: float
Total Size: 32400 bytes
            8100 values
Number of Dimensions: 2
Dimensions and sizes: [lat | 90] x [lon | 90]
Coordinates:
            lat: [-33.88806..-11.95309]
            lon: [-55.34121..-31.32556]
Number Of Attributes: 2
  long_name : TERRAIN ELEVATION
  units : m

How can I make this plot?

Best regards,
