libRadtran is freely available under the GNU General Public License. To install libRadtran on a Unix type system follow the unpacking instructions and the installation instructions. For the impatient:

1. Get the distribution

Here is the most recent version 2.0.5 from July 25, 2023.

Older versions are also still available (if asked for username and password, please try libRadtran for both).

If you download the package we ask you to send us a short eMail to let us know that you use the model. We have created a mailing list of libRadtran users in order to notify them of additions, changes, and bug fixes on an irregular basis.

2. Unpack the distribution

    gzip -d libradtran-x.yy.tar.gz
    tar -xvf libradtran-x.yy.tar

where x.yy is the version number.

3. Compile the distribution

    cd libRadtran-x.yy

4. Test the program

    make check (make sure to use GNU make)

5. Get additional modules if required

6. Required software to build libRadtran

The following software is required to successfully compile, link and run all of the libRadtran tools:

  • GNU make. The compilation might work with other make programs, but usually it doesn't.
  • The GNU C compiler (gcc). Other compilers might also work.
  • A Fortran compiler that is compatible with the C compiler. If a C compatible Fortran compiler is not available, f2c will do the job.
  • Flex - The Fast Lexical Analyzer. Is usually available for all flavours of Linux, under Mac, and for cygwin, but not necessarily installed by default. You may have to select installation of flex manually.
  • The Perl programming language, version 5.004 or later, is required to run the automatic test.
  • The netcdf library, including development package.
  • The GNU Scientific Library (GSL), including development package.

That's it. The example files and the documentation should give you enough knowledge to get started.

Users of Windows 95/98/NTXP/Vista/7 systems are asked to consult the installation of libRadtran under Windows instructions. Compilation under Windows is possible with only little more effort than on a Unix system. Please notice that we haven't updated this README (essentially because of laziness) because the Cygwin Stuff changes continuously - but we are sure that you will find your way!

To test libRadtran on Windows you may also try the Virtual Box. You find detailed installation instructions here.

For users of Windows 10 the Windows Subsystem for Linux is an option which allows installing libRadtran inside the subsystem. When using this subsystem be aware of the differences between Windows and Linux, e.g., with respect to pathnames (case-sensitivity, treatment of spaces, slash vs backslash).

7. Miscellaneous

The standalone version of cdisort 2.1.3 (the C language version of DISORT provided by Tim Dowling, updated July 25, 2013) may be obtained as well. See the included HOW_TO file for tips on installation and usage in a C environment. In publications, please cite Buras et al (2011, J. Quant. Spectr. Ra. Tran. 112, 2028-2034, doi:10.1016/j.jqsrt.2011.03.019).
