[ncl-talk] problems about converting ASCII to nc and plotting the nc file

[Dennis Shea]

[1] lat, lon, rain are all one-dimensional (1D)
[2] You are setting

     rain at lat2d = lat
     rain at lon2d= lon

    The reserved attributes @lat2d and @lon2d require two-dimensional
arrays.
    That is what the 2d means.

[3] You do not need to create a netCDF file for plotting.
      You can read the ascii and plot

See attached.
