Re: Dimension size error

A few things Chris.

First, your coordinate variable is not 2D. It is 1D (like it is stating in
your printVarSummary).
*Dimensions and sizes: [lon | 128]: 1D array*
*Dimensions and sizes: [lat | 64]: 1D array
*
So these should not be in your script*

  can_mean@lat2d = lat ; 2D coordinate arrays
  can_mean@lon2d = lon*
* lat2d = lat
  lon2d = lo*n

Secondly, your lonMin and lonMax is not within your 0 - 360 boundaries
*(Coordinates: lon: [ 0..357.1875])*

you have
* lonMin = -126
  lonMax = -119*

Hopefully, these small changes can guide you in the right direction. Without
your full script, I can only assume as to why certain errors are arising.
