[gradsusr] plot Cross section of topography

[Wesley Ebisuzaki - NOAA Federal]

Alireza,

My pgb file has the following variables

   tmpprs     .. temperature on 17 (hPa) pressure levels
   pressfc    .. surface pressure in Pa

set lat 30
set lon 0 360
set lev 1000 10
d tmpprs
orog.gs

------------ orog.gs ------------------
*
* maskout underground data for cross-sections
*
'define t1pm1=pressfc/100'
'set gxout grfill'
'set clevs  -1 1'
'set ccols  1 1'
'set ccols  0 0'
'd maskout(0,lev-t1pm1)'
'set gxout shaded'
---------  end orog.gs -------------------------------

       Wesley
