Plotting output from LLC2160

Hi all,
I have a very basic question. I am following this link to read in the output from the LLC2160 simulation. The 2d/3d output fields all have an extra dimension ‘face’. How do I “assemble” the values from the different faces to create something in (time,depth,lat,lon) format? [Or (time,lat,lon) for a 2d variable]
