An objective classification of radiation fog in distinct evolutionary stages during its life cycle based on reliable<br/> criteria is essential for various applications, for example for numerical fog modelling and fog forecasting.<br/> However, there have been up to now merely qualitative approaches for the distinction of different<br/> evolutionary stages in radiation fog. Measurements of the microphysical fog properties with an optical particle<br/> counter obtained from droplet measurement technologies together with recordings of the horizontal visibility<br/> (VIS) are statistically analyzed to determine individual evolutionary stages of radiation fog with consistent<br/> microphysical properties. The developed three-stage approach is based on a statistical change point analysis of<br/> the double sum curves of the VIS, the liquid water content, the droplet concentration and the mean radius of<br/> the drop size distributions. It could be shown that each of the three recorded radiation fog occurrences could<br/> be split into three consecutive phases from formation to dissipation, regardless whether the VIS or the<br/> microphysical properties were considered. Having featured consistent microphysical patterns, it could be<br/> assumed that the three separated phases of the single fog occurrence could be aggregated for radiation fog.<br/> Although this classification is statistically reliable, the dataset still has to be extended for a generalization<br/> concerning the separated evolutionary stages.
