# Author : Frédéric Hourdin/LMD/hourdin@lmd.jussieu.fr
# Usage  : install.sh
#
# bash installation script of the LMDZ model on a Linux PC.
# the model is downloaded in the following direcory tree
# $MODEL/modipsl/modeles/...
# using the "modipsl" infrastructure created by the "IPSL"
# for coupled (atmosphere/ocean/vegetation/chemistry) climate modeling
# activities.
# Here we only download atmospheric (LMDZ) and vegetation (ORCHIDEE)
# components.
#
# The sources of the models can be found in the "modeles" directory.
# In the present case, LMDZ5, ORCHIDEE and IOIPSL (handling of input-outputs
# using the NetCDF library.
#
# The script downloads various source files (including a version of NetCDF)
# and utilities, compiles the model, and runs a test simulation in a
# munimal configuration.
#
# Prerequisites : g95/pgf90/gfortran, ksh, wget , gunzip, tar, ... 
#
# Modif 18/11/2011
#    changes for option real 8.
#      We comopile with -r8 (or equivalent) and -DNC_DOUBLE for the GCM
#      but with -r4 for netcdf. Variable real must be set to 
#      r4 or r8 at the beginning of the script below.
