MODIFIED: November 1989 by Paul Lawson for LAPS/WISP. Routine +! now calculates adiabatic liquid water content +! (ADIABATIC_LWC) using cloud base pressure and grid-top +! temperature and pressure.

ADIABATIC_LWC in regions where T < 0 C adjusted +! using an empirical algorithm by Marcia Politovich. +! +! Subroutine is now hardwired for stratiform cloud only. +!
