LMie (Linearized Mie) computes the scattering properties for polydisperse homogeneous spherical particles using Mie theory. What sets LMie apart from the many other Mie implementations available is that in addition to the typical scattering quantities LMie has the option to analytically generate derivatives of these quantities with respect to the input parameters. This makes LMie convenient for sensitivity studies and remote sensing retrievals of particle properties. LMie is also parallelized over the size distribution integration with OpenMP for shared memory systems such as multi-core workstations and with MPI for clusters. LMie is coded in C while C/C++ and Fortran 77/90 interfaces are available. LMie is free and open source software and is licensed under the GNU General Public License.

The first LMie beta release (version 0.90) is available for download.

July 8, 2011

The LMie source code will be available for download soon.


The following is a list of some LMie's more interesting features:


The source code can be downloaded for Linux/Unix/MacOS as lmie-0.9.tar.gz or for Windows as lmie-0.9.zip.

Alternatively, the LMie git repository may also be accesed on github.

See the user manual for documentation on how to compile the library and link it to your programs.


The LMie manual can be read online as an HTML document or may be downloaded as a PDF. Alternatively, the LMie distribution comes with both the HTML and PDF forms of this documentation in the "doc/" subdirectory.

The "examples/" subdirectory contains a simple example program that calls LMie and uses some of its basic features. A example exist for each of the language interfaces supported.
