Compling CLAVR-x

Installing CLAVR-x

This page will take you the steps to install the most recent version of CLAVR-x. It assumes you are installing this into the directory refered to as $CLAVRX_HOME (i.e. $CLAVRX_HOME = /home/heidinger/clavrx on my system).

CLAVR-x is currently run using the G95, Intel or xlf90 Fortran 90 compilers. It has not been tried on other compilers. If you do try compiling using other compilers, you will need to modidy the configure script or manually modify the Makefile.

1. Obtain latest code source. New users can obtain the location of the source code from Andrew Heidinger.

2. Extract this into a directory (i.e. src) under $CLAVRX_HOME

3. Run the configure script.

Running the configure script with the --help option provides the following output

CLAVR-x configure script. Run it in order to configure CLAVR-x build process. It should be executed in the CLAVR-x source directory.

Usage: configure [command line options...]

Command line options:

   --with-ifort[=<path>]
         Intel FORTRAN compiler will be used. A path to the executable is
         optional.

   --with-g95[=<path>]
         GNU FORTRAN 95 compiler will be used. A path to the executable is
         optional.

   --with-xlf90[=<path>]
         IBM AIX FORTRAN compiler will be used. A path to the executable is
         optional.

   --hdflib=<directory>
         Path to the directory where HDF library files are stored.
         Default is /usr/local/hdf/lib.

   --with-szip[=<directory>]
         Path to the SZIP library, if required by the HDF library. If
         directory not given, the argument of '--hdflib' option used.

   --help
         Display this help message.

4. Compile

After running the configure script, your Makefile should be ready to go. In the source directory, type "make" and if all works the three main executables should appear in $CLAVRX_HOME.
The three main executables are

- clavrxorb: processed the orbits into the selected output files

- comp_asc_des: compiles mapped orbital files into daily ascending and descending files. This only takes data from one satellite.

- comp_time: compiles mapped orbital files into global files comprised of data within the specified time window. This can include data from multiple satellites.
