<p><span class="fontstyle0">We describe a universal meteor simulation tool set named A</span><span class="fontstyle0">SMODEUS </span><span class="fontstyle0">and present several of its possible use cases. The toolset consists of a Monte-Carlo simulator of meteoroids entering the Earth</span><span class="fontstyle2">&#8217;</span><span class="fontstyle0">s atmosphere, functions for transformation to observer-centred coordinate frames representing virtual views of the sky, application of observational bias effects and a number of statistical tools for analyses of produced data sets and comparison to real-world data. The simulation has already been used in several areas of research, most notably estimates of meteoroid </span><span class="fontstyle3">fl</span><span class="fontstyle0">ux and de-biasing of real-world meteor observations and in investigation of how varying the initial properties of meteoroids affects the resulting meteors. It lends itself to many more possible applications, such as assessment of selection bias in ground-based observing systems, investigation of models of meteor </span><span class="fontstyle3">fl</span><span class="fontstyle0">ight and ablation, and evaluation of mass and population indices of meteor showers.</span></p>
