All SMOKE programs can be controlled by input environment variables, and the run scripts control these variables. The program documentation in Chapter 5, SMOKE Utility Tools, Chapter 6, SMOKE Core Programs, and Chapter 7, SMOKE Quality Assurance include the available environment variable settings for each program.

The example run scripts contain most of the major script settings needed for running SMOKE. The major exception to this is the UAM_* settings needed for Smkmerge and Smk2emis, when running for UAM-V and CAM_X. These can be added to the scripts as needed.
