I speculate you are overwriting the generated png file with each iteration.

---
[1] Move the following before the 'do' loop

wks = gsn_open_wks("png","diff")

or

[2] Keep it where it is but make the line

wks = gsn_open_wks("png","diff_"+sprinti("%0.2i", it) )

Hi


I am trying to use the following script to generate a temperature difference between two files. This script should generate 24 plots instead of just one. When I add "it" in tc2= wrf_user_getvar(a,"T2",it) then I get this error "Subscript out of range, error in subscript #0". This could be because I used NCO to generate these files which stripped out the time dimension since I have averaged them over time. I would appreciate if some one can help me out here. Kindly note that I donot intend to waste someone personal time.


do it=0,23
 wrf_file1 = "UTC_" + it + ".nc"
 a = addfile(wrf_file1, "r")
 wrf_file2 = "../OmerForest/UTC_" + it + ".nc"
 b=addfile(wrf_file2,"r")

tc2= wrf_user_getvar(a,"T2",0)
tcf= wrf_user_getvar(b,"T2",0)
diff=tc2-tcf
wks = gsn_open_wks("png","diff")
res=True
plot = gsn_csm_contour(wks,diff,res)
 end do
