[ferret_users] How to mask land in a vertical section plot ?

[Sudev Das M P <devdas.pnr@xxxxxxxxx>]

Dear All,

I have a script meant for plotting vertical section of temperature. I don't know how to do the land masking using "go fland" command or any other similar command. Please see the attached figure. Please give me some suggestions how I can do this. 

The script I am using is given below. 
!====================================================================

!-----------------------------------------------------------------------------------------------------
! 1) Load data 
!-----------------------------------------------------------------------------------------------------
use "temp.nc"

!-----------------------------------------------------------------------------
! 2) Set the region for plotting.
!-----------------------------------------------------------------------------
 SET REGION/X=48E:98E/Y=10N

!-----------------------------------------------------------------------------
!Defining the levels that we want to show in the color bar.
!-----------------------------------------------------------------------------
define symbol t_levels = (-inf)(4,28,2)(inf)

!-----------------------------------------------------------------------------
! 3) Plotting the vertical section
!-----------------------------------------------------------------------------
contour/line/fill/palette=rainbow/lev=($t_levels)/k=1:24/L=1/nokey/nolab temp

--------------------------------------------------
--------------------------------------------------
==========================================================================
Thanks and regards,
Sudev
