McArtim is an acronym for **M**onte **C**arlo **A**tmospheric **R**adiative **T**ransfer **I**nversion **M**odel.
It is a RTM that has been designed to simulate the radiative transfer
in the atmosphere of the Earth in the UV/vis/NIR spectral range with Monte Carlo
methods. The method is described in detail in the McArtim paper. The aim is to support
the analysis and evalution of scattered sun light measurements. Certain output quantities of the programs can be used in combination
with the DOAS technique.

This webpage shall provide the necessary informations to use and run McArtim. It furthermore gives an overview on how the program results can be used in combination with numerical (inversion) methods to reconstruct parts of the atmospheric state from a spectroscopic measurement.

On **January 8th 2015** I finished my PhD thesis on McArtim. The **thesis** can be downloaded here.
The **defense talk** is here.
