what does the 3rd dimension represent ?

Hi,
I have a satellite data that stores lat / lon information in 3-D
array and I'm wondering how such data can meet the CF convention.
Following the
http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.4/ch05s02.html
page example convention, here's the description of my data:
-------------------------
dimensions:
d0 = 447 ;
d1 = 3 ;
d2 = 360;
lev = 18 ;
variables:
float V(lev,d0,d1,d2) ;
T:long_name = "Precipitable Water" ;
T:units = "cm" ;
T:coordinates = "lon lat" ;
float lev(lev) ;
lev:long_name = "pressure level" ;
lev:units = "hPa" ;
float lon(d0,d1,d2) ;
lon:long_name = "longitude" ;
lon:units = "degrees_east" ;
float lat(d0,d1,d2) ;
lat:long_name = "latitude" ;
lat:units = "degrees_north" ;
-----------------------------------------------
My question is, should lat / lon coordinate variables be always 2-D
array in CF-convention for two dimensional coordinate system?
Thanks,
