To all CHAMMP and ARM PIs Jim Hack has finalized the long awaited single column model tool based on the NCAR CCM3. This project was a CHAMMP-supported activity to provide stronger links between the ARM and CHAMMP research communities. The model and documentation can be found on http://www.cgd.ucar.edu/cms/sccm/sccm.html Jim is looking for users and welcomes feedback to hack@ncar.ucar.edu. Have fun, Dave Bader
