Advection Tests

Hello,I am currently running a modified version of CAM3. I would like to check that added aerosols are sedimenting properly but this is complicated by advection. Is there a way to turn advection "off" and/or are there any good advection or circulation tests that can be performed to make sure everything is running correctly.Thanks for any help!

cam3.1 had a feature (which is no longer supported in cam) to declare "non-advected" constituents.  This is done via an argument to the cnst_add call.  The treatment of "non-advected" constituents is that they are advected by the physics parameterizations, but not by the large scale dynamics.That said, probably the best way to determine exactly what the sedimentation process is doing to aerosols is to directly output the aerosol fields before and after the sedimentation process.
