Dynamic reverse gas stack model for portable chemical detection devices to locate threat and point-of-source from effluent streams

A system comprising:

• a molecule detector adapted to generate information representative of a presence of one or more target molecules based on one or more samples of an environment;
• a positioning system configured to generate location information representative of one or more locations, each of the one or more locations corresponding to a location where a sample of the one or more samples of the environment was obtained;
• and
• a processor communicatively coupled to the molecule detector and to the positioning system, wherein the processor:
• receive the information representative of the presence of one or more target molecules and the location information;
• determines, based on the information representative of the presence of one or more molecules and the location information, a reverse gas stack model for the one or more target molecules;
• and
• predicts a location for a source or effluent for the one or more target molecules based on the reverse gas stack model.
