Calling Tree

The following is a brief outline of the calling sequence for the main CLM driver routine contained in driver.F90 (Section A.53). Conditionally-executed routines are denoted by the inclusion of the associated pre-processor variable in brackets after the routine name. An exclamation point preceding the variable reverses its meaning. The comprehensive listing of source code prologs contained in Appendix A provides a brief synopsis of the functionality provided by each of the routines listed below.
