[ferret_users] Trying to visualize data on cubed-sphere grid

[Gary Strand <strandwg@xxxxxxxx>]

I'm playing around with some data that's on a cubed-sphere grid, and am wondering if the description of the grid is causing the usual "Y coord field lies in different plane from data to be plotted" error when using the "shade ts,lon,lat" command.

The data of interest and the longitudes and latitudes are all described as one-dimensional vectors, i.e., a 1-D array of N points:

yes? use test.nc 
yes? show data
     currently SET data sets:
    1> ./test.nc  (default)
 name     title                             I         J         K         L         M         N
 TS       Surface temperature (radiative)  1:777602  ...       ...       1:1       ...       ...
 LAT      latitude                         1:777602  ...       ...       ...       ...       ...
 LON      longitude                        1:777602  ...       ...       ...       ...       …

and 'ncdump -h' shows:

prompt> ncdump -h test.nc | egrep "(lon|lat|TS)"

        float TS(time, ncol) ;

                TS:units = "K" ;

                TS:long_name = "Surface temperature (radiative)" ;

                TS:cell_methods = "time: mean" ;

        double lat(ncol) ;

                lat:long_name = "latitude" ;

                lat:units = "degrees_north" ;

                lat:axis = "Y" ;

        double lon(ncol) ;

                lon:long_name = "longitude" ;

                lon:units = "degrees_east" ;

                lon:axis = "X" ;

Giving lon and lat the appropriate "axis" attributes doesn't change anything about how FERRET sees the data.

Any suggestions appreciated!
