# !MODULE: Makefile (in the ISOROPIA/ subdirectory)
#
# !DESCRIPTION: This makefile compiles the ISOROPIA code.  
#  Object files (*.o) are bundled into the libIsoropia.a library 
#  (located in the LIB directory).  Module files (*.mod) are copied to 
#  the MOD directory. 
#\\
#\\
# !REMARKS:
# To build the programs, call "make" with the following syntax:
#                                                                             .
#   make TARGET [ OPTIONAL-FLAGS ]
#                                                                             .
# To display a complete list of options, type "make help".
#                                                                             .
# %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
# %%% NOTE: Normally you will not have to call this Makefile directly,     %%%
# %%% it will be called automatically from the Makefile in the directory   %%%
# %%% just above this one!                                                 %%%

# Makefile uses the following variables:
#                                                                             .
# Variable   Description
# --------   -----------
# SHELL      Specifies the shell for "make" to use (usually SHELL=/bin/sh)
# ROOTDIR    Specifies the root-level directory of the GEOS-Chem code
# HDR        Specifies the directory where GEOS-Chem include files are found
# LIB        Specifies the directory where library files (*.a) are stored
# MOD        Specifies the directory where module files (*.mod) are stored
# AR         Sys var w/ name of library creator program (i.e., "ar", "ranlib")
# MAKE       Sys var w/ name of Make command (i.e, "make" or "gmake")
# R8         Specifies the c
#
# !REVISION HISTORY: 
#  21 Dec 2009 - C. Carouge  - Initial version
#  22 Aug 2011 - R. Yantosca - Add "-fp-model source" flag for IFORT compiler,
#                              which prevents random numerical noise
#  25 Aug 2011 - R. Yantosca - Remove -fp-model source flag here, as this is
#                              now added to FFLAGS in Makefile_header.mk
