2. Evaluation of the new lagrangian code

f.e11.F2000C5.ne30_ne30.vert-adv.001

CAM5.2
use non langrangian code
nsplit=5
qsplit=4
rpslit=0

w/ obs
w/ FV 1d

This is the CAM5.2 release.
The ne30 simulation is competitive with FV 1deg except for the stratocumulus deck

f.e11.F2000C5.ne30_ne30.vert-adv.002

CAM5.2
use langrangian code for vertical advection
nsplit=1
qsplit=4
rpslit=5

w/ obs
w/ ne30 non-lagrangian
w/ FV 1d

The langrangian code really helps with the stratocumulus deck.
Basically the stratocumulus are quasi indistinguishable between ne30 and FV 1deg

The taylor diagrams are significantly improved at ne30 compared to fv 1deg
