The basics of a description for CM1.
I believe Luke has a publication we can cite,
There is some question about 'u0' vs. 'u10'

+Cloud Model 1 (CM1) version 18 (CM1r18) is compatible with the DART.
+CM1 is a non-hydrostatic numerical model in Cartesian 3D coordinates
+designed for the study of micro- to mesoscale atmospheric phenomena
+in idealized to semi-idealized simulations. The CM1 model was
+developed and is maintained by George Bryan at the National Center
+for Atmospheric Research (NCAR)
+Mesoscale and Microscale Meteorology Laboratory (MMM).
+The model code is freely available from the CM1 website:
+<a href=http://www2.mmm.ucar.edu/people/bryan/cm1/>
+http://www2.mmm.ucar.edu/people/bryan/cm1</a>
+and must be downloaded and compiled outside of DART.
+<br />
+<br />
+This model interface and scripting support were created by Luke Madaus.
+<strong>Thanks Luke!</strong>
+<br />
+<br />
+Several modifications to the CM1 namelist <em class=file>namelist.input</em>
+are required to produce model output compatible with DART. The values are described here
+and and example is shown below. Using CM1 output files as a prior
+ensemble state in DART requires each ensemble member to produce a
+restart file in netCDF format (<em class=code>&param9: restart_format=2</em>)
+only containing output at the analysis time (<em class=code>&param9: restart_filetype=2</em>).
+The only required state variable to be updated is potential temperature (<em class=code>theta</em>)
+and requires the following namelist setting to ensure this is present in the
+CM1 restart files: (<em class=code>&param9: restart_file_theta = .true., restart_use_theta = .true.</em>).
+<br />
+<br />
+Additional state variables that have been tested within DART include
+<em class=code>ua, va, wa, ppi, u10, v10, t2, th2, tsk, q2, psfc, qv, qc, qr, qi qs, and qg</em>.
+At present, observation times are evaluated relative to the date and time specified in section
+<em class=code>&param11</em>.
+Observation locations are specified in meters relative to the domain origin as defined in
+<em class=code>&param2: iorigin</em>.
