Re: [error]fatal:(lon) is not a named dimension in variable (var).

Hi Vanúcia,
To add on to what Dennis is saying: From the printVarSummary you should be
able to see if lon is a named dimension of var. I am guessing that it is
not, and that NCL is failing at this line because of it:
new_var = linint2_Wrap(var&lon,var&lat,var,True,new_lon,new_lat,0)
