[1] NCL *automatically* converts the data to a
    regular N80 Gaussian grid. NCL uses an ECMWF
    supplied code to do this.
[2] Why not use ds118.0? It is already on a 2.5 x 2.5 grid
    ERA40 2.5 Degree Latitude-Longitude Gridded Surface
              and Single Level Analysis from ECMWF
[3] If you want to convert from GRIB to netCDF use NCL's
    ncl_grib2nc ... a command line operator.
good luck
