Test netcdf-4 coordinate variables and dimensions with an example
from the CF conventions.
Here's the example from the CF conventions:
dimensions:
xc = 128 ;
yc = 64 ;
lev = 18 ;
variables:
float T(lev,yc,xc) ;
T:long_name = "temperature" ;
T:units = "K" ;
T:coordinates = "lon lat" ;
float xc(xc) ;
xc:axis = "X" ;
xc:long_name = "x-coordinate in Cartesian system" ;
xc:units = "m" ;
float yc(yc) ;
yc:axis = "Y" ;
yc:long_name = "y-coordinate in Cartesian system" ;
yc:units = "m" ;
float lev(lev) ;
lev:long_name = "pressure level" ;
lev:units = "hPa" ;
float lon(yc,xc) ;
lon:long_name = "longitude" ;
lon:units = "degrees_east" ;
float lat(yc,xc) ;
lat:long_name = "latitude" ;
lat:units = "degrees_north" ;
