[ncl-talk] mjoclivar_5.ncl

[Sujata Mandke]

Dear NCL community,
Greetings!

 I am using NCL script  ”mjoclivar_5.ncl” from “MJO clivar” 
application examples on NCL website. 
I wish to make time-longitude plot from time 1 June 2018 to 25 June 2018.  

I have few questions on different settings in this NCL script.

(i) There was an error due to missing values as follows
(0)	band_pass_hovmueller: currently, missing data not allowed: nMsg=1986

(To solve this problem i have added following and the error disappeared) 
X = where(ismissing(X), 0.0, X) 

(ii)It is given in sample script that we need to keep 
enough buffer. So what time should be set for  
“twStrt” and “twLast”.  However my input data
 file contains data from 1-1-2002 to 14-7-2018. 
so i have no option but to keep twLast=20180714. 

(iii) I wish to filter in 30-60day band so i had set
  bpf     = (/30,60,201/)
(this was giving error -  “fatal:wgt_runave_n: 
The length of wgt must be less than or equal to the 0-th dimension of x”)
So i have changed as follows
  bpf     = (/30,60,101/)

(iv)Then script run with following error but figure is not created
fatal:Subscript out of range, error in subscript #0
fatal:An error occurred reading tValL

I am using NCL version 6.4.0 on linux machine.
Please help in this regard. 
Any suggestion would be of great help.
 Many thanks in advance.
