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 2.0.1 from April 4, 2016.
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 ./configure make
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:
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!
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.
