Re: How to plot the topography in Y-Z plate?
Hi,
The following journal file is what we use to overlay a land-sea mask for
Levitus data. It works for vertical sections too.
Shankar.
------------------------------------------------------------------------
! NOTE: for a contour plot in the XY plane BELOW the surface, you must supply
! the first argument to this GO script.
! usage: GO fland_levitus k=N (where N is the required level)
! or GO fland_levitus z=Z (where Z is the required depth)
! GO fland_levitus (in other cases)
\cancel mode verify
! fland_levitus.jnl - a land mask for the LEVITUS dataset (overlay or "basemap")
! 1/97
! Description: Plot/overlay an an area-filled continental map using LEVITUS mask
! usage: arg1 arg2 arg3 arg4 arg5
! GO fland_levitus [z=lo:hi] [palette] [overlay_style] [x=lo:hi] [y=lo:hi]
! arg1 - depth limits - specify as for any FERRET depth range
! use either k=*:* or z=*:*
! arg2 - palette - may be any palette on your system. Normally solid colors
! like black, gray,red, etc. (see Fpalette '*') default=gray
! arg3 - overlay_style - "basemap", "transparent", or "overlay" (default)
! arg4 - longitude limits - specify as for any FERRET longitude range
! arg5 - latitude limits - specify as for any FERRET latitude range
! examples:
! GO fland_levitus ! default - color gray, overlay
! GO fland_levitus k=1 ! MASK for surface
! GO fland_levitus k=1 red ! palette red.spk, overlay
! GO fland_levitus z=0:1000 red basemap ! color red, basemap
! GO fland_levitus z=1000 gray transparent ! color gray, transparent mask
! GO fland k=1 gray overlay x=30e:100w y=20s:20n
! Note : The transparent option creates a see-through overlay land mask
! check the overlay/basemap/transparent option
query/ignore $3%overlay|overlay|basemap|transparent<3rd argument of GO fland_levitus must be "overlay", "basemap", or "transparent"%
! save data set
set data/save
! save region
define region/default levitus
! set data for MASK
use levitus_mask.nc
set region/l=1
shade/nolab/nokey/levels="(-0.5,0.5,1.0)"$1" |*>/*"/pal=$2"gray"$3"/overlay|basemap> |*>/overlay"$4" |*>/*"$5" |*>/*" $3"MASK|transparent>if mod(i+j,2) eq 0 then MASK|*>MASK"
! cancel MASK data set
cancel data levitus_mask.nc
! restore region
set region levitus
! restore original data set
set data/restore
set mode/last verify
! END of fland_levitus.jnl
