# Makefile for ncep_forcing_pp

# Greg O'Donnell    May, 2000
# Modified: Justin Sheffield (justin@princeton.edu)
#
# Requires the operating system (OS) as a command line argument
# NOTE: this works for Gnu Make and may not work for other versions
#
# Command line arguments: you can switch certain parts of the code on/off by
# using the LOCATION and FORCING arguments to the make command.
# e.g. make LOCATION=NCEP FORCING=REALTIME
# LOCATION refers to NCEP or elsewhere, such as PU (Princeton University).
# This is required because the pathnames of the forcing files are different at NCEP
# FORCING refers to the forcing dataset (REALTIME or RETRO). This is used
# to switch on/off code that applies to only to a certain dataset (e.g. using
# EDAS solar radiation only for July 1999 to Feb 2000 for the realtime data).
