Re: does not have an associated coordinate variable

The error is telling you exactly what the problem is:

    lat = lat1

The variable "lat" already exists, because of previous code. You are now trying to assign "lat1" to it, which is a different size.

I'm not sure why you have that line. Can't you just do:

; lat = lat1
    wgty = cos(0.01745329*lat1)

If you still have a question about lag regression, please post a new ncl-talk question. People will otherwise see the old subject and think you are still asking about coordinate variables.
