Abstract This contribution starts with a short overview on cometary dust modelling and then focuses on the application of coma modelling with respect to in-situ measurements of cometary dust and ground based observations. The fountain model, valid for the dynamics of small cometary dust particles, is discussed. Models using Keplarian theory for the motion of the dust particles are outlined and the ESOC coma model is presented. Some direct applications of this model to analyse the results of the recent spacecraft flybys of comet Halley, as dust flux profiles, particle ground tracks and envelope positions, are shown. To compare the model with ground-based astronomical observations, the utilization of the ESOC coma model for the generation of synthetic images is demonstrated and some future prospects of this technique are outlined.
