[ncl-talk] NCL Error

[JP Kalb]

The error I am getting for the wrf_omega and w_to_omega is that both are undefined.  Also, when I try to multiply my w by rho. I am getting an error saying "Fatal: mul: Dimension size, for dimension number 0, of operands does not match" JP Kalb

 Including more of the script will/would help.  
Sounds like bprime is an array, but there was no way for anyone to know that from your initial post. 
Therefore where is probably what you actually want.  e.g.
bprime = where( bprime .lt. 0, 0, bprime)   ; see documentation for whats going on here. 



Also, for some reason wrf_omega does not want to work.
No one can do anything with this statement.  Include an error message, an example of why it’s not working, some sample data.

 I tried that change but I am getting a scalar issue since I want to look at vertical motion at different levels. JP Kalb

 A small correction to Karin's answer: there is a extra ending
parenthesis. It should be

if (bprime .lt. 0) then
  bprime = 0
end if
