First of all I assume you mean the CCM3.10.11 branch with CCM3.6.6 physics
correct? As announced in...
http://www.cgd.ucar.edu/cms/ccm3/news/ccm3.6.6_forIBM.shtml
> 1. Are there significant differences between CCM3.10 and CCM3.2?
As far as code or as far as science? The code is quite a bit different.
The difference in simulations are the documentated differences between
CCM3.2 and CCM3.6. See the CCM news page...
http://www.cgd.ucar.edu/cms/ccm3/news/ccm3.6.shtml
for info on the differences. Note that there aren't significant changes
in the climate. Compare for example the cases...
/ROSINSKI/csm/ccm3/ccm3527 (new model -- bit-for-bit with CCM3.6.6)
and
/OLSON/ccm3/sld012b (old model -- bit-for-bit with CCM3.2)
Note, the CCM3.10.11 branch code was tested to be bit-for-bit with the
CCM3.6.6 code.

Not at NCAR anyway...
