I am a new user of NCL and is at the learning stage.
I have installed ncl 5.1.0 successfully and have checked with ng4ex gsun01n.
I am trying to learn to use NCL for WRF output.
I tried to use the following script:
1 ;********************************************************
2 ; WRF: simple plane view of the pressure field
3 ; at a specific time and level. No map background.
4 ;********************************************************
5 load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
6 load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
7 begin
8 ;********************************************************
9 ; open file
10 ;********************************************************
11 f = addfile ("wrfout_d01_2007-01-31_12.nc", "r")
12
13 ;********************************************************
14 ; Read character variable Times
15 ; Convert to type string for plotting purposes
16 ;********************************************************
17 times = chartostring(f->Times) ; built-in function
18
19 ;********************************************************
20 ; Read Pressure at Time=12, level=0, convert to hPa
21 ;********************************************************
22 p = f->P(12,0,:,:) ; import data + meta info
23 p = p*0.01 ; demo: convert to hPa
24 p_at_units = "hPa" ; update units attribute
25
26 ;********************************************************
27 ; create plots
28 ;********************************************************
29 wks = gsn_open_wks("ps" ,"WRF_cn") ; ps,pdf,x11,ncgm,eps
30 gsn_define_colormap(wks,"BlAqGrYeOrReVi200"); select color map
31
32 res = True ; plot mods desired
33 ;;res_at_gsnMaximize = True ; uncomment to maximize
34 size
35 res_at_tiMainString = times(12) ; main title
36 plot = gsn_csm_contour(wks,p,res)
37
38 res_at_cnFillOn = True ; turn on color
39 res_at_cnLinesOn = False ; turn contour lines
40 res_at_gsnSpreadColors = True ; use entire color map
41 res_at_lbLabelAutoStride = True ; let NCL determine label
42 spacing
43 plot = gsn_csm_contour(wks,p,res)
44 end
45
but I am getting the error
[mmittal_at_localhost ~/NCL]$ ./exam1
./exam1: line 1: syntax error near unexpected token `;'
./exam1: line 1: `;********************************************************'
I am using cshell. Script is the file exam1 and does not have line numbers.
What am I missing?
Thank you for your help.
