The error messages from GrADS
Notice: Implied interpolation for file rot01b.ctl
 Interpolation will be performed on any data displayed from this file
gancgrid error: nc_get_vara_double failed; NetCDF: Start+count exceeds
dimension bound
Data Request Error:  Error for variable 't2m'
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = t2m
Cannot plot color bar: No shading information


but if instead I put the following (same file is on my disk) it WORKS
excellently!
