Building the model with new chemistry

The tutorial "5 Fun Things to do with WACCM" has been corrected.

Slide 12 explains how to change model chemistry based on the base chemistry pre-processor input file. The name of that file was incorrect in the original version of this presentation posted to the WACCM working group website.

The following line shows how to copy the correct base chemistry input file from its path to the user's $CASEDIR:

cp $CCSMROOT/models/atm/cam/chem_proc/inputs/waccm3_57spc_JPL06_ccmval_clbrfam.in my_waccm_mech.in

Attempting to use a different input file as the basis for user-defined chemistry may result in the model quickly crashing with the failure of the implicit solver.
