In the current industrial age, hazardous substances are produced, stored and shipped in large quantities. An accidental or deliberate release of such substances can result in a chemical cloud that endangers civil population and first responder. By means of classical analytical methods (e.g. Ion-Mobility Spectrometry, Gas Chromatography – Mass Spectrometry, test papers) chemical clouds are only measureable if a detector operator enters that cloud. Using these standard techniques, the dimension and movement of such a cloud are not assessable.
