#
# Makefile for RTTOV wrapper program used by Surface Temperature procedure

# -----------------------------------------------------------------------------

# You must update the following variables below according to the local RTTOV installation and compiler

# RTTOV_VERSION   RTTOV version number
# RTTOVDIR        root directory for RTTOV binaries, libraries, modules, includes

# FC              compiler command name
# FFLAGS          compiler specific flags: -I$(RTTOVDIR)/mod -I$(RTTOVDIR)/include are mandatory
# LDFLAGS_ARCH    flags for linker

# BINDIR          directory to store the binary file

# If RTTOV was compiled against the HDF5 or external LAPACK libraries this is
# handled automatically using the contents of Makefile.local.

# -----------------------------------------------------------------------------

# The RTTOV_DATA_PATH environment variable is required.
